An electric current i(1) can flow either...

An electric current `i_(1)` can flow either direction through loop (1) and induced current `i_(2)` in loop (2). Positive `i_(1)` is when current is from 'a' to 'b' in loop (1) and positive `i_(2)` is when the current is from 'c' to 'd' in loop (2) In an experiment, the graph of `i_(2)` against time 't' is as shown below

Which one(s) of the following graph could have caused `i_(2)` to behave as give above.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
`phi_(2)=Mi_(1) implies i_(2)=1/R(-(dphi_(2))/(dt))`
`i_(2)=-M/R(dI_(1))/(dt)`
