WebNov 8, 2024 · As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: (5.4.8) E i n d u c t o r = − L d I d t. With the current increasing, the derivative is positive, and since L is always positive, a voltage drop requires a minus sign. 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: swapping of 2 numbers using temp variable
