Question

The magnetic flux through a circuit of resistance 'R' changes by an amount $\Delta \Phi$ at a time $\Delta t$. Then the total quantity of electric charge Q that passes any point in the circuit during the time $\Delta t$ is represented by

• A. $Q=\frac{\Delta \Phi }{R}$
• B. $Q=\frac{\Delta \Phi }{\Delta t}$
• C. $Q=R.\frac{\Delta \Phi }{\Delta t}$
• D. $Q=1R.\frac{\Delta \Phi }{\Delta t}$

Answer 1

The correct option is A $Q=\frac{\Delta \Phi }{R}$

$I=\frac{e}{R}=\frac{1}{R}\left|\frac{\Delta \varphi }{\Delta t}\right|=\frac{\Delta Q}{\Delta t}$
$Q=\frac{\Delta \varphi }{R}$
