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 the above

Answer 1

Answer: (B)

Time

Answer 2

We know that $e = \frac{d\varphi}{dt}$

But e=iR and $i = \frac{dq}{dt} \Rightarrow \frac{dq}{dt}R = \frac{d\varphi}{dt}$ ⇒$\mspace{6mu} dq = \frac{d\varphi}{R}$
