Questions
An ideal coil of 10 H is connected in series with a resistance of 5 and a battery of 5V. 2 second after the connection is made, the current flowing in ampere in the circuit is
detailed solution
Correct option is B
We know that i=imax1−e−t/τ Here τ=LR=105=2sec. So, at t=2sec. and imax=VR=55=1 we get i=11−e−2/2=1−e−1Talk to our academic expert!
