Answer #1

You didn't mention that resistance were either in parallel or in series...

First I consider them in parallel...

When they are in parallel , the potential will be equal across both resistor and equal to 8 Volt.

Second case Now I am going to consider them in series...

When they are in series then equivalent resistance is R = R1 + R2

R = 87 + 44

R = 131ohm

Current I = V/R= 10/131

I = 0.076 amp

Voltage across R2

V2 = I × R2

V2 = 0.076 × 44

V2 = 3.36 voltage
