Question

Explain parallel RC circuit with AC supply.​

Answer 1

Explanation:

This guide covers The combination of a resistor and capacitor connected in parallel to an AC source, as illustrated in Figure 1, is called a parallel RC circuit. ... In a pure capacitor the current leads the voltage by 90 degrees, while in a pure inductor the current lags the voltage by 90 degrees.

Answer 2

Answer:

An RC circuit (also known as an RC filter or RC network) stands for a resistor-capacitor circuit. An RC circuit is defined as an electrical circuit composed of the passive circuit components of a resistor (R) and capacitor (C), driven by a voltage source or current source.

Due to the presence of a resistor in the ideal form of the circuit, an RC circuit will consume energy, akin to an RL circuit or RLC circuit.This is unlike the ideal form of an LC circuit, which will consume no energy due to the absence of a resistor. Although this is only in the ideal form of the circuit, and in practice, even an LC circuit will consume some energy because of the non-zero resistance of the components and connecting wires.

Series RC Circuit

In an RC series circuit, a pure resistor having resistance R in ohms and a pure capacitor of capacitance C in Farads are connected in series.

SERIES R-C CIRCUIT

Here I is the RMS value of the current in the circuit.

V_R is the voltage across the resistor R.

V_C is the voltage across the capacitor C.

V is the RMS value of the supply voltage.
