Question 273: Electromagnetic Induction

Question

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

Accepted Answer

According to Faraday's law of electromagnetic induction,
$\begin{aligned}
& \varepsilon=\frac{\Delta \phi}{\Delta t} \
& \mathrm{IR}=\frac{\Delta \phi}{\Delta \mathrm{t}} \
& \mathrm{I}=\frac{\Delta \phi}{\Delta \mathrm{t} 	imes \mathrm{R}} \
& \mathrm{I} 	imes \Delta \mathrm{t}=\frac{\Delta \phi}{\mathrm{R}}
\end{aligned}$
$	herefore$ The total quantity of electric charge passing through the circuit is
$\mathrm{Q}=\frac{\Delta \phi}{\mathrm{R}}$

Answer

$-\frac{\Delta \phi}{\Delta t}+R$

Answer

$\frac{\Delta \phi}{\mathrm{R}}$

Answer

$\frac{\Delta \phi}{\Delta t}$

Answer

$\frac{\Delta \phi}{\Delta t} 	imes R$

Electromagnetic Induction

The magnetic flux through a circuit of resistance 'R' changes by an amount \Delta \phi in the time \Delta t. The total quantity of electric charge 'Q' which passes during this time through any point of the circuit is
