Question

Current in $R_3$ in the shown circuit

• A. just after closing the switch is zero
• B. long after closing the switch is zero
• C. just after closing the switch is $\frac{E}{R_3}$
• D. long after closing the switch is $\frac{E}{R_3}$

Answer 1

Answer: (A), (B)

The correct options are
A just after closing the switch is zero
B long after closing the switch is zero

Just after switch is closed, $L$ is open circuit and $C$ is short circuit
Just after
After long time $C$ is open and $L$ is short circuit
