An AC circuit, or alternating current circuit, is a type of electrical circuit where the current flow periodically changes direction. This is in contrast to a DC circuit, where the current flows in only one direction.
In a series AC circuit, all components are connected in a single loop, meaning the current flow through each component is the same. In a parallel AC circuit, the components are connected in separate branches, meaning the current can flow through each branch independently.
The impedance of an AC circuit is calculated by adding the resistive, capacitive, and inductive components together using the following formula: Z = √(R^2 + (Xl - Xc)^2), where R is the resistance, Xl is the inductive reactance, and Xc is the capacitive reactance.
The phase difference in an AC circuit refers to the difference in timing between the voltage and current waves. In a purely resistive circuit, the voltage and current waves are in phase, meaning they peak and trough at the same time. In a circuit with inductive or capacitive components, the voltage and current waves can be out of phase, leading or lagging behind each other.
The frequency of an AC circuit refers to the number of complete cycles the current flow goes through in one second. As the frequency increases, the reactance of inductive and capacitive components also increases, leading to changes in the overall impedance and current flow in the circuit.
