Question

In electromagnetic induction, the induced charge in a coil is independent of

• A. Change in the flux
• B. Time
• C. Resistance in the circuit
• D. None of these

Answer 1

Answer: (B)

We know that $e=\frac{d \varphi}{d t}$
But $e=i R$ and $i=\frac{d q}{d t}$
$\Rightarrow \frac{d q}{d t} R=d q=\frac{d \varphi}{R}$
