Questions
In an LR circuit, time constant is that time in which current grows from zero to the value (where I0 is the steady state current)
detailed solution
Correct option is A
Current at any instant of time t after closing an L-R circuit is given by I=I0I-e-RLt Time constant, t=LR∴I=I0I0-e-RL×LR=I01-e-1=I01-1e=I01-12.718=0.63I0=63% of I0Talk to our academic expert!
