Academics

Q1. An RL circuit consists of a switch, an emf source Eo, a 4 kΩ resistor, and a 5 H inductor. If the potential across resistor is 16 V 5 ms after switch is closed, find out the source emf, Eo.

Q2. An AC generator consists of 100 turns of wire of area 0.090 m2 and total resistance 12 Ω. The loops rotate in a magnetic field of 0.50 T at the constant angular speed of 60 revolutions per second. Find out the maximum induced emf.
