An RL series circuit is initially relaxed. A step voltage E is applied

1.	An RL series circuit is initially relaxed. A step voltage E is applied. If is time constant, voltage across R and L will be equal at =
Answer» vR = E(1 - e-t/t) and vL = E e-t/t or 1 - e-t/t = e-t/t. This happens at t = t in 2.
