Question

Three resistors R1= 3 Ω, R2= 5 Ω, and R3 = 2 Ω are connected with 150 V power supply. What is the voltage across R2 ?

a.75 V
b.15 V
c.10 V
d.32 V

Answer 1

The answer will be c.10V

Answer 2

If the resistors are in series, it's 75 volts.

If they're in parallel, it's 150 volts.

You never told us series or parallel.
