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:
