A coil used for control applications is being supplied by a 24-V DC supply. When the coil is disconnected from the source using a switch, sparks occur at the switch. In an attempt to solve this problem, a 100 microfarad capacitor is connected in parallel to the coil. If the coil has an inductance of 0.1 Henrys and a resistance of 20 Ohms, explain if the addition of the capacitor helped solve the problem. Determine the voltage across the switch to aid your explanation.
