#### Question

A resistance of 20 ohms has a current of 2 amperes flowing in it. What potential difference is there between its ends?

#### Solution

Here:

Resistance, *R* = 20 Ω

Current, *I* = 2 A

Substituting these values in the Ohm's equation, *V*/*I* = *R*:

Potential difference, *V* = *I* x *R* = 2 x 20 = 40 V

Is there an error in this question or solution?
