Tjhe capacitor C is initially without charge. X is now joined to Y for a ong time, during which H1 heat is produced in the resistance R. X-Y connection is removed and X is now connected to Z for a long time, during wihch heat H2 is produced in R. Wihat is relation of div and H2.
H1=H2
H1=H2/2
H1=2H2
H1=H2/4

Dear student 
 
When X is joined to Y for a long time (charging), energy stored
in the capacitor is equal to heat produced in R=H1.
When X is joined to Z (discharging), the energy stored in
C=(H1) reappears as heat (H2) in R. Thus, H1=H2
