Task id16564

In the alternating current circuit (Fig.) the external resistance is R = 100 Ohm, the capacitance of the capacitor C = 20 μF. At the moment when the e.m.f. current source E = 100 V, current I = 0.5 A is directed as shown in Fig. , and increases at a rate of dI/dt = 200 A/s, and the charge of the capacitor q = 0.6 mC. Find the inductance of the coil L. Neglect the internal resistance of the current source and the resistance of the coil. Assume that Ohm's law is satisfied for a slowly varying alternating current.
