A) \[Q=\frac{\Delta \phi }{R}\]
B) \[Q=\Delta \phi .R\]
C) \[Q=\frac{R\Delta t}{\Delta \phi }\]
D) \[Q=\Delta t.R\]
Correct Answer: A
Solution :
From Faradays law of EMI. emf induced in the circuit is \[e=\frac{\Delta \phi }{\Delta t}\] If\[R\]is the resistance in the circuit, then \[I=\frac{e}{R}=\frac{\Delta \phi }{\Delta t.R}\] So, the total amount of charge passing through the circuit is \[Q=I\times \Delta t=\frac{\Delta \phi }{\Delta t.R}.\Delta t\] \[\Rightarrow \] \[Q=\frac{\Delta \phi }{R}\]You need to login to perform this action.
