Question

How do I solve both these problems?

1. Charges on the capacitors in three oscillating LC circuits vary as follows: (1) q = 2 sin(5t), (2)

q =4 sin(3t), (3) q = sin(4t) (with q in coulombs and t in seconds). Rank the circuits

according to (a) the current amplitude and (b) the period, greatest first.

2. In an oscillating LC circuit with C = 240 μF, the current is given by , i= 4sin(450t+0.6)

where t is in seconds, i in amperes, and the phase constant in radians. (a) How soon after t = 0

will the current reach its maximum value? What are (b) the inductance L and (c) the total

energy??

Thanks
