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 $e=\frac{d\phi }{dt}$
But $e=iR$ and $i=\frac{dq}{dt}$
$\Rightarrow \frac{dq}{dt}R=dq=\frac{d\phi }{R}$
