Power in AC circuits Power in AC (alternating current) circuits is a key concept that relates to the flow of electrical energy. In AC circuits, the voltage and current alternate periodically, resulting in a sinusoidal waveform. The instantaneous power in an AC circuit can be calculated using the following formula: Instantaneous power (P) = Voltage…
LCR Series circuit An LCR series circuit is an electrical circuit that consists of three components connected in series: an inductor (L), a capacitor (C), and a resistor (R). Here are some important aspects of an LCR series circuit: Understanding these aspects of an LCR series circuit is important for analyzing its behavior, calculating parameters…
Mutual Inductance Mutual inductance is a phenomenon that occurs when two or more coils of wire are placed close to each other. It describes the ability of one coil to induce an electromotive force (emf) in another coil through the changing magnetic field produced by the current flowing in the first coil. The mutual inductance,…
Lenz Law Lenz’s Law is a fundamental principle in electromagnetism that describes the direction of an induced current in a conductor when it is exposed to a changing magnetic field. It states that the induced current in a conductor will flow in a direction that opposes the change in magnetic flux that caused it. When…
Faraday’s law Faraday’s law refers to a fundamental principle in physics that describes the relationship between a changing magnetic field and the induction of an electromotive force (EMF) or voltage in a conducting loop or circuit. It was discovered by the English scientist Michael Faraday in the 19th century. Faraday’s law states that the magnitude…
