Question:

A parallel-plate air condenser whose each plate has an area S = 100 cm2 is connected in series to an ac circuit. Find the electric field strength amplitude in the capacitor if the sinusoidal current amplitude in lead wires is equal to I m = 1.0 mA and the current frequency equals w = 1.6.107 s-1
