Vout = (C1/C1+C2).Vin Inductive Voltage Dividers The capacitive voltage divider circuit is shown below.īy using these capacitors which are connected in the series, we can determine the RMS voltage drop across every capacitor in terms of their reactance once they connected to a voltage source.Ĭapacitive dividers do not allow DC input.Ī simple capacitive equation for an AC input is The capacitive reactance formula can be derived asĮach capacitor’s reactance can be measured by the voltage as well as the frequency of the AC supply & substitute them in the above equation to get the equivalent voltage drops across every capacitor. Not like resistive voltage divider circuits, capacitive voltage dividers works with a sinusoidal AC supply because the voltage division among the capacitors can be calculated with the help of capacitors reactance (X C) that depends on the AC supply’s frequency. Currently, these dividers are applicable in touchscreen-based tablets, mobiles, and display devices. Usually, these are used to reduce extremely high voltages for providing a low output voltage signal. VR1 = Vs (R1/ R1+R2) Capacitive Voltage DividersĬapacitive voltage divider circuit generates voltage drops across capacitors which are connected in series with an AC supply. Similarly, the voltage drop across the R1 resistor can be calculated as So now can calculate the voltage drop across the R2 resistor in the circuit So the flow of current is the same in both resistors. The flow of current through the series circuit is I = V/R according to Ohm’s Law. So the flow of current in the circuit can be given as By applying KVL & Ohms Law to this circuit, we can measure the voltage drop across the resistor. Using a voltage source, a voltage supply is applied to this circuit. Therefore, it provides a voltage drop (I*R) across every resistive. So the flow of current in these resistors will be the same. In the resistive divider circuit, the two resistors like R1 and R2 are connected in series. The resistive voltage divider circuit is shown below. This circuit uses the voltage divider rule to measure the voltage drop across every series resistor. The basic type of a passive voltage divider circuit can be built with two resistors which are connected in series. This is a very easy and simple circuit to design as well as understand. The above equation states that the Vout (o/p voltage) is directly proportional to the Vin (input voltage) and the ratio of two resistors R1 and R2. By using the following equation, we can find the output voltage. The voltage divider rule equation accepts when you know the three values in the above circuit they are the input voltage and the two resistor values. V4(t)= V(t) R4/R1+R2+R3+R4 Voltage Divider Equation Voltage division rule for above two resistor circuit Voltage Divider Rule using Three Resistors This voltage divider rule can be extended to circuits that are designed with more than two resistors. The above circuit shows the voltage divider between the two resistors which is directly proportional to their resistance. The voltage divider involves two important parts they are the circuit and the equation. Applying this rule can also solve simple circuits thoroughly The main concept of this voltage divider rule is “ The voltage is divided between two resistors which are connected in series in direct proportion to their resistance. The voltage divider rule is used to solve circuits to simplify the solution. The input voltage can be transmitted between the two resistors in the circuit so that the division of voltage takes place. This circuit is also called a potential divider. The resistors in the circuit can be connected in series whereas a voltage source is connected across these resistors. This circuit can be designed with two resistors otherwise any passive components along with a voltage source. Definition: In the field of electronics, a voltage divider is a basic circuit, used to generate a part of its input voltage like an output.
