Electro Magnetic Induction And Alternating Currents Question 160
Question: A sinusoidal voltage V(t) = 100 sin (500t) is applied across a pure inductance of L=0.02H. The current through the coil is:
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: B
Solution:
-
In a pure inductive circuit current always lags behind the emf by
If
Now, given v(t) = 100 sin (500 t) and
