The sum of the voltage drops in the cir-
cuit is equal to the given supply voltage.
Total Resistance R = R1+R2
= 100+200
R = 300Ω
Current I = V /R
= 300 /300 = 1A
Voltage drop V1
= I × R1
= 1 × 100 = 100V
Voltage drop V2
= I × R2
= 1 × 200 = 200V
V = V1 + V2
300 V = 100V + 200 V
300 V = 300 V
The sum of the voltage drops in the circuit is equal to the supply voltage.
