Question

Initially the circuit is in steady state. When the switch S is closed, the heat generated in the circuit will be:

• A. $\frac{{\epsilon }^{2}C}{2}$
  
• B. $2{\epsilon }^{2}C$
  
• C. $\frac{3{\epsilon }^{2}C}{2}$
  
• D. zero

Answer 1

The correct option is D

zero

As switch is closed potential difference across capacitor is still 'E' $V_A-V_B=E$
