WebApr 14, 2024 · In an \( \mathrm{LR} \) circuit current at \( \mathrm{t}=0 \) is \( 20 \mathrm{~A} \). After \( 2 \mathrm{~s} \) it reduces to \( 18 \mathrm{~A} \). The time... WebSpecifically, the time it takes the current in a circuit, containing only resistance and inductance to increase to 63.2 percent (or decrease to 36.8 percent) of its maximum value is known as the time constant. The time constant is determined by the ratio of circuit inductance to circuit resistance. The mathematical equation is:
