Question

A 2 μ F capacitor is charged to 50 V by a battery. The battery is removed after capacitor is fully charged. At time t = 0 , a 10 mH coil is connected in series with the capacitor. The maximum rate at which the current changes in the circuit is, 2000 A s - 1, 5000 A s - 1, 2500 A s - 1, 10000 A s - 1

MARKS App · Accepted Answer

Maximum potential across capacitor = 50 V . Maximum rate of current flow will require maximum potential along the inductor. Therefore, L d I d t = 50 ⇒ d I d t = 50 L = 5000 A s - 1
