Electro Magnetic Induction And Alternating Currents Question 571
Question: If a current of 10 A flows in one second through a coil, and the induced e.m.f. is 10 V, then the self-inductance of the coil is [CPMT 2000; Pb. PMT 2001; MHCET 2003]
Options:
A) $ \frac{2}{5}H $
B) $ \frac{4}{5}H $
C) $ \frac{5}{4}H $
D) 1 H
Show Answer
Answer:
Correct Answer: D
Solution:
$ |e|,=L\frac{di}{dt}\Rightarrow 10=L\times \frac{10}{1}\Rightarrow L=1H $
