, Voltage Division Rule – (Two Resistors in Series)
Consider two resistors R1 and R2 connected in series.
Req = R1 + R2
V V
Let, I be the circuit current, I = =
Req R1 + R2
V R1
Voltage across R1, V1 = IR1 = R1 = V
R1 + R2 R1 + R2
V R2
Voltage across R2, V2 = IR2 = R2 = V
R1 + R2 R1 + R2
Hence in a series circuit of two resistors,
voltage in one resistor = total voltage x that resistance
sum of the two resistors
This circuit is also called voltage divider circuit
