1.	Please help.Consider the circuit shown in figure There are three switches S1 S2 S3 Match the columns
Answer» Explanation: When switch S 1 is closed and the others are open, the INDUCTOR is essentially out of the circuit and what remains is an RC circuit. The TIME constant is τ C =RC. When switch S 2 is closed and the others are open, the capacitor is essentially out of the circuit. In this case, what we have is an LR circuit with time constant τ L =L/R. FINALLY, when switch S 3 is closed and the others are open, the resistor is essentially out of the circuit and what remains is an LC circuit that oscillates with period T=2π LC . Substituting L=Rτ L and C=τ C /R, we obtain, T=2π

Answer»

Explanation:

When switch S

is closed and the others are open, the INDUCTOR is essentially out of the circuit and what remains is an RC circuit.

The TIME constant is τ

=RC. When switch S

is closed and the others are open, the capacitor is essentially out of the circuit. In this case, what we have is an LR circuit with time constant τ

=L/R.

FINALLY, when switch S

is closed and the others are open, the resistor is essentially out of the circuit and what remains is an LC circuit that oscillates with period T=2π

. Substituting L=Rτ

and C=τ

/R, we obtain, T=2π
