Explanation:
It is given that,
Inductance,
RMS value of voltage,
Frequency, f = 60 Hz
We need to find the energy stored at t = (1 /185) s. It is assumed that energy stored in the inductor is zero at t = 0. So,
The current flowing through the inductor is given by :
I = 0.091 A
Energy stored in the inductor is,
U = 0.000165 Joules
Hence, this is the required solution.
Answer:
The average induced emf in the loop is 0.20 V
Explanation:
Given:
Radius of loop m
Magnetic field T
Change in time sec
According to the faraday's law,
Induced emf is given by
Where magnetic flux
( here
)
Where
We neglect minus sign because it's shows lenz law
V
Therefore, the average induced emf in the loop is 0.20 V
