Answer 2

The current produced in wire is 0.5 A.

Explanation:

The relationship between energy transferred, current, voltage and time is given by

$E=Vit$

Given, Energy (E) = 15 J, voltage (V) = 1.5 V and time (t)= 20 s.

Substitute the given values, we get

 $15J=1.5V\times i\times20s$

$i=\frac{15}{30}$

i = 0.5 A.

Thus, the current produced in wire is 0.5 A.
