Explanation:
You mean the electric Potentials of two points are 100V ( point x) and 20V( point y)
Since potential of X is higher than Y, conventional current is said to flow from X to Y
Potential difference = 80 -20 = 60V
=> V = 60V
Power = 160W. ( since joules per second is = watt)
I = ?
Power = V^2 / R
=> R = 60 x 60 / 160
= 22.5 ohms
V = IR
=> I = V/R
=> I = 60 / 22.5
=> I = 2.66... A
