Displacement current Displacement current is a concept in electromagnetism that was introduced by James Clerk Maxwell in his equations describing the behavior of electric and magnetic fields. It is a term used to explain the relationship between changing electric fields and magnetic fields. Displacement current arises when there is a time-varying electric field in a…
Transformer A transformer is an electrical device used to transfer electrical energy between two or more circuits through electromagnetic induction. It consists of two or more coils of wire, called the primary and secondary windings, that are wound around a common core. Key points about transformers: It’s important to note that transformers are a broad…
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…
