#### Question

If a potential difference of 10 V causes a current of 2 A to flow for 1 minute, how much energy is transferred?

#### Solution

Here:

Potential difference, *V* = 10 V

Current, *I* = 2 A

Time, *t* = 1 minute = (1 x 60) s = 60 s

We know that the amount of energy transferred is equal to the work done.

Now:*V* = *W*/*Q*

Or *W* = *V* x *Q*

= *V* x *I* x *t* (since *Q* = *I* x *t*)

= 10 x 2 x 60

= 1200 J

Thus, the amount of energy transferred is 1200 J.
