WebFeb 24, 2012 · An RL circuit (also known as an RL filter or RL network) is defined as an electrical circuit consisting of the passive circuit elements of a resistor (R) and an inductor (L) connected together, driven by a voltage source or current source. 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. ray petty https://kozayalitim.com
