Question

What is the potential difference across an electrical load that has a resistance of 4 O and a current of 3 A flowing through it

Answer 1

Answer:

12 V

Explanation:

Resistance (R) = 4 ohm

Current (I) = 3A

Potential difference= ?

V=IR

V=4×3

V=12 V

Answer 2

Given,

The resistance of the circuit = 4 Ω

Current flowing through the circuit = 3 A

To Find,

The potential difference across the circuit.

Solution,

By using the ohm's law

V = R*I

where

V is the potential difference across the circuit

R is the resistance of the circuit

I is the current flowing through the circuit.

So,

V = 4*3

V = 12 volts.

Hence, the potential difference across the circuit is 12 volts.
