Electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows only desired frequencies. In other words a filter is a circuit which allows only a certain band of frequencies. The main applications of the filters are at audio equalizers and in sensitive electronic devices whose input signals should be conditional. These filters are mainly categorized into 2 types. They are Active filters and passive filters.

Passive filters do not contain any amplifying elements just they are made up of Resistor, Capacitor and inductors passive elements. These filters will not draw any additional power from the external battery supply. The Capacitor will allow the high frequency signals and inductor allows low frequency signals. Similarly inductor restricts the flow of high frequency signals and capacitor restricts the lower frequency signals. In these filters output signal amplitude is always less than the amplitude of the applied input signal.

The Voltage Divider Rule formula VDR shows how the voltage distributes among different resistors in a series circuit. Similarly, the Current Divider Rule formula CDR shows how current distributes in a parallel circuit. VDR and CDR Formulas are the tools for voltage and current distribution in series and parallel circuits.

Each resistor in series combination has a different voltage drop across it. The individual voltage drop of resistors adds up to source voltage. While the current for the series circuit remains the same throughout the divider circuit as discussed earlier. In a parallel resistor, the voltage across each resistor is the same as the source voltage. But current divides such that the summation of individual resistor current is always equal to source current.

In the previous post, series combination , we have solved the electrical circuit shown and found the following parameters for the circuit. By looking closely at these numbers, you will observe that the voltage drop is different from each other and the summation of all of them is equal to the voltage applied to that circuit source. The question is, how do these voltages relate to each other? The answer is Voltage Divider Rule Formula.

Suppose the above series circuit such that we are interested in finding voltage drop V 3 across R 3. The voltage divider rule calculator is a web-based tool for calculating voltage across resistor Rx.

A voltage divider is a circuit that divides a voltage between two resistors. And it will let you calculate voltages at many different points in a circuit — which is often needed to understand it. I have to admit that I have made more use of my practical experience with building circuits than I have from the electronics theory I learned at the university. But this formula is one of the few electronics formulas I actually use on a regular basis.

I recommend you memorize this formula. It will come in handy often. Or bookmark this voltage divider calculator if you prefer the easy way ;. One example of a voltage divider circuit is for analog sensors. For example, the thermistor is a temperature sensor. It changes its resistance based on the temperature.

Or you can combine a known resistor with a photoresistor. The photoresistor changes resistance based on the amount of light it detects. This way, you have a circuit that increases or decreases the voltage based on light.

In this tutorial, we will learn about one of the commonly known and used circuits in electronics i. We will see a basic Voltage Divider Circuit and analyze its functionality. There are a lot of basic circuits in Electronics that might look simple on paper but serve a big purpose practically. One such circuit is the Voltage Divider Circuit or sometimes known as the Potential Divider Circuit.

Before going further into the understandings of a Voltage Divider Circuit, let us first take a problem and see how can we resolve it with the help of a Potential Divider. Consider a Microcontroller that runs on 5V power supply. For the sake of simplicity, let this Microcontroller be Arduino and the ATmegaP on Arduino Uno board requires a 5V power supply. Now let us assume you want to implement a project that involves a Bluetooth Module like Bluetooth Controlled Home Appliances or Bluetooth based DIY Robotic Arm.

One of the commonly used Bluetooth Modules for DIY projects is HC The HC Bluetooth Module can be connected to Arduino Uno using UART Communication i. Pins 0 and 1 of Arduino Uno RX and TX respectively. These pins should be connected to corresponding TX and RX pins of the HC Bluetooth Module. But there is a problem here.

The two resistor voltage divider is used often to supply a voltage different from that of an available battery or power supply. In application the output voltage depends upon the resistance of the load it drives. The voltage divider is a very important basic circuit, and exploring the calculation above with various values can give you insight into a large number of practical circuit applications.

One practical consideration is that a larger value of R 2 compared to R 1 will give you a larger output voltage. But if your load resistance R L is smaller than R 2 , you will diminish the output voltage and require a larger current and total power from the power supply. You would find upon exploration that for a given set of values for the voltage divider R 1 and R 2 , you will get more power to the load if you decrease the load resistor R L but is comes at the expense of higher current and power from the power supply.

Note: To avoid dealing with so many short circuits, divider resistors with value zero will default to 1 when the voltage is changed and the load will default to They can be changed back to a zero value if you wish to explore the effects of short circuits. Ohms are indicated as the resistance unit, but kilohms are more common and of course the calculation is the same.

A Voltage Divider Circuit uses resistors to reduce voltage, and is the most common circuit used in electronics. Voltage Divider can be used to do lot of things like to create a volume control circuit or generate reference voltage and much more. Voltage Divider are also used in analog circuits to get variable voltage outputs. This circuit works fine with both AC and DC input voltage, in this input voltage value is converted into another voltage value.

In Voltage Divider Circuit the output voltage is always depends upon the proportion of the amount of resistance. Like if you have taken two equal value of resistor you will receive exactly half of the input voltage at output. An electrical equivalent circuit of voltage divider is given below:. As you can see the voltage divider circuit consists of two resistors connected in series with a voltage tap between them.

And, the input voltage is applied across the resistor R 1 and R 2. Therefore, we can observe that the output voltage is the voltage drop across the resistor R 2. The voltage across R 1 and R 2 will be equal to the input voltage value applied to the voltage divider circuit. The formula of Voltage Divider Equation for finding the value of output voltage will be expressed as:.

Deriving Voltage Divider Equation. The basis for the voltage divider circuit is the Ohm’s Law.

For a power supply, you want the voltage to stay at the chosen level no matter if the circuit you connect has a.

Another configuration that can provide high bias stability is voltage divider bias. Instead of using a negative supply off of the emitter resistor, like two-supply emitter bias, this configuration returns the emitter resistor to ground and raises the base voltage. So as to avoid issues with a second power supply, this base voltage is derived from the collector power supply via a voltage divider. Let’s derive the equations for the load line. First, let’s consider the saturation and cutoff endpoints.

What resistances are left to limit the current? The divider voltage yields the base voltage. We then subtract the 0. But how do we know if the divider is lightly loaded in the first place without going through the Thevenin equivalent? The approximation yields 4. Once again the proportions between voltage and current for the Q point appear to be proper when compared against the endpoints.

To create the PNP version of the voltage divider bias, we replace the NPN with a PNP and then change the sign of the power supply.
