When a coil is connected to a D.C. source of e.m.f. 12 volt, then a current of 4 ampere flows in it. If the same coil is connected to a 12 volt, 50 cycle/s A.C. source, then the current flowing in it is 2.4A . The self inductance of the coil will be

A steady 4 A flows in an inductor coil when connected to a 12 V source as shown in figure. If the same coil is connected to an ac source of 12 V , 50 "rad"//s a currentd of 2.4 A flows in the circuit as shown in figure2. Now after these observations , a capacitor fo capacitance (1)/(50) F is connected in series with the coil and with same AC source as shown in figure 3. The resistance of the coil is:
