Flux; (in Weber's) in a closed circuit of resistance varies with time (in seconds) according to the equation . What is the magnitude of the induced current in seconds?
Step 1: Given
Resistance,
Time
Equation according to which flux is varying,
Step 2: Find the emf
The derivative of flux gives us the emf.
Hence,
Substituting the time,
Step 3: Find the magnitude of induced current
Using Ohm's law,
Hence, the magnitude of current induced is
