List of top Physics Questions on LCR Circuit

In an LC circuit, the inductance \( L \) is 2 H and the capacitance \( C \) is 4 μF. What is the frequency of oscillation of the circuit?

The amplitude of the charge oscillating in a circuit decreases exponentially as $Q = Q_0 e^{-Rt/2L}$, where $Q_0$ is the charge at $t=0s$. The time at which charge amplitude decreases to 0.50 $Q_0$ is nearly:
[Given that $R = 15 \Omega$, $L = 12 mH$, $ln(2) = 0.693$]

A logic circuit provides the output y as per the following truth table:

A	B	Y
0	0	1
0	1	0
1	0	1
1	1	0

The expression for the output Y is:
