Question: The magnetic flux through a circuit of resistance R changes by an amount Δφ in time Δt , Then the total quantity of electric charge Q , which passing during this time through any point of the circuit is given by [Haryana CEE 1996; CBSE PMT 2004]

Options:

A) Q=ΔφΔt

B) Q=ΔφΔt×R

C) Q=ΔφΔt+R

D) Q=ΔφR

Show Answer

Answer:

Correct Answer: D

Solution:

We know that e=dφdt But e=iR and i=dqdtdqdtR=dφdt

Þ  dq=dφR
