Question

Three resistors have resistance of R, 2R, and 3R, are connected to a 12 volt energy source as shown in the circuit diagram. The current is 2 A. What is the potential difference across the resister with resistance R?

a. 2 volts
b. 4 volts
c. 6 volts

Answer 1

2volts

Step-by-step explanation:

Let us assume the resistor are in series

Equivalent resistance = R + 2R + 3R

Equivalent resistance = 6R

Since different voltage flows through the resistors

V = IR

Given V = 12V

I = 2A

Assume R = 1ohms

V = IR

V = 2 * 1

V = 2volts

Hence the potential difference across the resister with resistance R is 2volts
