Define 1 joule work , 1 joule energy and 1 watt power.

one joule work is said to be done when the force of one newton applied to a body to displace through the ditance of 1m.

one joule energy is the energy that can do 1j work .

The power of a body that can do 1j work in 1 sec is called one watt power.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
