Question

an inductor is connected to a direct voltage source through a switch. now larger emf is induced when switch is opened. please explain the reason....hurry

Answer 1

When the switch will open, current will start flowing hence larger emf is induced

Answer 2

Answer:

when switch will be opened the current delivered by the external voltage will stop, this will cause a significant change of flux in considerably less amount of time. The rate of change of flux is emf so , this rate of change of flux will be much greater and hence a large emf is generated wheen switch is opened
