Magnetic flux (in weber) in a closed circuit of resistance 20 
varies with time t(s) as 
= 8t 2 - 9t + 5. The magnitude of the induced current at t = 0.25 s will be______mA
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(250)
At t = 0.25 s
Emf = - [(16 x 0.25)-9] = 5V
Current =
