320J
Explanation:
Final Potential - Initial potential = work done/charge
charge=current * time
V=120-100=20
work done=20*16=320J

The amount of work done is 320 J.
Explanation:
The relationship between potential difference and work done is given as
Here, is the change in potential difference and q is the charge.
As charge is given as
q = it
Here i the current and t is the time.
So relation becomes,
Given i = 8 A, t = 2 s and .
substitute the given values, we get
W = 320 J.
Thus, the amount of work done is 320 J.
