Embibe Experts Solutions for Exercise 3: EXERCISE 7.3

Switch is in position $A$ for a long time. At time $0$, it is switched to position $B.$ Find time period of resulting charge oscillation.

Switch is in position $A$ for a long time. At time $0$, it is switched to position $B.$ Find the maximum charge which will accumulate on capacitor.

Two capacitor with initial charges $C{V}_0$ and $2C{V}_0$ as shown in figure are connected across an inductor of inductance $L.$ Find time period of oscillation and maximum current through the circuit

A $16 \mathrm{\mu }\text{F}$ capacitor is charged to $20 \mathrm{V}$. The battery is then disconnected and a pure $40 \mathrm{mH}$ coil is connected across the capacitor, so that LC oscillations are set up. The maximum current in the coil is
 

In oscillating LC circuit, the total stored energy is $U$ and maximum charge upon capacitor is $Q.$ When the charge upon the capacitor is $\frac{Q}{2}$, the energy stored in the inductor is
