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:
