Question

Because the current in the equivalent resistor of Sample Problem A

is 0.50 A, it must also be the current in each resistor of the original
circuit. Find the potential difference across each resistor.

Answer 1

V1= IR1= 0.50×2 = 1 V

V2= IR2= 0.50×4= 2 V

V3= IR3= 0.50×5= 2.5 V

V4= IR4= 0.50×7 = 3.5 V
