The magnetic flux through a circuit of resistance $R$ changes by an amount $\Delta \phi$ in a time $

Question

The magnetic flux through a circuit of resistance $R$ changes by an amount $\Delta \phi$ in 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\

Professor PC Thomas Classes · Answer

(b) : Induced emf is given by $V=\frac{\Delta \phi}{\Delta t}$\ current $(i)=\frac{Q}{\Delta t} \Rightarrow \frac{\Delta \phi}{\Delta t} 	imes \frac{1}{R}=\frac{Q}{\Delta t}$\ $\Rightarrow \quad Q=\frac{\Delta \phi}{R}$\
