Question

calculate the heat developed in a current carrying conductor in 3 seconds

a) 2A current flows through it when it is connected to 50 volt supply.

b) Find the resistance of the conductor.

c) find the charge flows through the conductor during the intervals.​

Answer 1

Answer:

Explanation:Correct option is

D

Nt

Mi

​

 

Induced emf = Mutual Inductance ×  

dt

di

​

 

e=M  

dt

di

​

 

In given problem, for N turns,

e=M  

t

i

​

 

So, induced emf per turn in the coil is Mi/Nt.
