A resistor–inductor circuit (RL circuit), or RL filter or RL network, is one of the simplest analogue infinite impulse response electronic filters. It consists of a resistor and an inductor, either in series, driven by a voltage source.
RL circuits form a single-pole filter. Depending on whether the reactive element is in series with the load, or parallel with the load will dictate whether the filter is low-pass or high-pass.
Frequently RL circuits are used for DC power supplies to RF amplifiers, where the inductor is used to pass DC bias current and block the RF getting back into the power supply.
Mr. Lalit Sardana(IIT JEE AIR 243) is teaching you the topic Series combination of resistor and inductor. He has explained phasor diagram and sine equation that are related to the topic in this video. The students would not find it difficult to understand as the topic is explained to them in a very easy language. This topic is generally asked in 11th and 12th std. exams as well as the competitive exams like IITJEE, AIEEE, AIPMT, NEET, AFMC, MPPET, and many others.
