Question
The magnetic flux through a circuit carrying a current of 2.0 A is 0.8 weber. If the current reduces to 1.5A in 0.1 s, the induced emf be:
Options
A.2.0 V
B.4.0 V
C.8.0 V
D.none of the above
Solution
Flux corresponds to 2A is = 0.8 weber
flux corresponds 1.5 A is = 0.6 weber |e| =
= 2.0V
flux corresponds 1.5 A is = 0.6 weber |e| =
= 2.0VCreate a free account to view solution
