A LCR circuit is equivalent to a damped pendulum. In an LCR circuit the capacitor is charged to Q 0 and then connected to the L and R as shown below : C L R If a student plots graphs of the square of maximum charge ) Q ( 2 Max on the capacitor with time (t) for two different values L 1 and L 2 (L 1 > L 2 ) of L then which of the following represents this graph correctly ? (plots are schematic and not drawn to scale)

1. 2 Max Q t L 1 L 2
2. 2 Max Q t L 2 L 1
3. 2 Max Q t L 1 L 2
4. 2 Max Q t Q 0 (For both L 1 and L 2 )

Correct answer: 2 Max Q t L 1 L 2
