Overview
An alternating voltage of 100 V and 100/\pi Hz is applied to a circuit consisting of a 12.5 \mu F capacitor in parallel with a 3 Ω and 20 mH coil (see attached figure). Calculate and detail all the steps:
a) The currents that circulate through the capacitor and through the coil, and the total current.
b) the power dissipated in the circuit.
c) the capacity that the capacitor should have so that the total current is minimum and the value of this intensity.
