Question 309: Electrostatics & Capacitance

Question

A capacitor C is fully charged with voltage V
0
. After disconnecting the voltage source, it is connected
in parallel with another uncharged capacitor of capacitance $${C \over 2}$$. The energy loss in the process
after the charge is distributed between the two capacitors is :

Accepted Answer

Heat loss = $${1 \over 2}\left( {{{{C_1}{C_2}} \over {{C_1} + {C_2}}}} ight)V_0^2$$
= $${1 \over 2}\left( {{{C 	imes {C \over 2}} \over {C + {C \over 2}}}} ight)V_0^2$$
= $${1 \over 6}CV_0^2$$

Answer

$${1 \over 2}CV_0^2$$

Answer

$${1 \over 4}CV_0^2$$

Answer

$${1 \over 3}CV_0^2$$

Answer

$${1 \over 6}CV_0^2$$
