Question
An LCR circuit is equivalent to a damped pendulum. In an LCR circuit, the capacitor is charged to Q0 and then connected to the L and R as shown.
If a student plots graphs of the square of maximum charge ( QMax2 ) on the capacitor with time (t) for two different values L1 and L2 (L1 > L2) of L then which of the following represents this graph correctly? (Plots are schematic and not drawn to scale)
Solution
D.
Inductance is inertia of circuit. It means inductance oppose the flow of charge, more inductance means decay of charge is slow.
In option (d), in a given time to 
.
So, L1> L2
