To Explain:
The reason behind why a running vacuum cleaner after unplugging from a wall outlet creates more spark than that of a lighted lamp would produce the spark after being unplugged from the wall.
Answer to Problem 19SSC
The inductance of motor in a vacuum cleaner,
Explanation of Solution
Introduction:
An inductor has a coiled wire around iron.Motors have a fixed coil of insulated wire that surrounds another coil of wire which is insulated.In case motor induction is too high, and motor current cannot be delivered in needed time. The current is given too fast to the motor when a device is with low inductance.
Vacuum cleaner comprises of the motor while light lamp comprises of the bulb.
The motor has higher inductance in a vacuum cleaner that creates electromotive forces which causes spark and bulb to have low self-inductance, that is why there is no electromotive force and does not cause a spark.
Conclusion:
Hence as the vacuum cleaner consisting of a motor and it has high inductance which creates a
