The two identical parallel plates are given charge as shown in figure. If the plate area of either face of each plate is `A` and seperation between plates is `d`, then find the amount of heat liberate after closing the switch.

Text Solution

Verified by Experts

The correct Answer is:
`(1)/(2)(q^(2)d)/(in_(0)A)`

Before closing the switch
After closing the switch
`{:(U_(i)=(q^(2))/(2C),,rArr,,U_(i)(q^(2)d)/(2in_(0)A)):}`
`H = U_(1) - U_(f) = (q^(2)d)/(2 in_(0)A)`
