Answer 1

Answer:

A. 60/7 should be the correct answer.

Explanation:

Let the voltage difference between the resistors be V1 and V2 respectively.

Therefore,

V1+V2 = 20

I×R1 + I×R2 = 20

I(R1+R2) = 20

I = 20/(4+3) = 20/7 Ampere.

Therefore, V2 = R2×I = 3×20/7 = 60/7

V1 = R1×I = 20/7 ×4 = 80/7
