VOLTAGE DIVISION RULE

A QUICK INTRODUCTION TO THE VOLTAGE DIVISION RULE AND HOW TO APPLY IT ON A CIRCUIT.

In a series of resistors, the same current flows through each of them resulting in a voltage drop across them.

According to the voltage division rule, the voltage across any resistor in a series connection of resistors shall be equal to the ratio of the ohmic value of the resistor divided by the equivalent resistance of the circuit.

VOLTAGE DIVISION RULE

Assume a circuit with two resistors R1 and R2 connected in series with voltage V applied across it. Total resistance = R1+ R2 Let the total current be I. Voltage Vin = I.(R1 +R2) Voltage across R1, V1 = I.R1 = V.R1 / (R1+R2) Voltage across R2, V2 = I.R2 = V.R2 / (R1+R2)
