### FAQ

What is Time Constant of LR Circuit?
The Time Constant of LR Circuit formula is defined as the time required for the current flowing in the LR series circuit to reach its maximum steady state value is equivalent to about 5 time constants or 5τ and is represented as tau=L/R or Time constant of L-R circuit=Inductance/Resistance. Resistance is a measure of the opposition to current flow in an electrical circuit. Its S.I unit is ohm and Inductance is the tendency of an electric conductor to oppose a change in the electric current flowing through it.
