Question

What is an RC Series circuit?

Answer 1

In order to answer this question we need to understand that all electric or electronic circuits or structures are afflicted by a few forms of “time-put off” between it enter and output when a signal or voltage, both non-stop, (DC) or alternating (AC) is first applied to it. The resistor is a linear component whereas the inductor and capacitor have storage capacity.

Complete step by step answer:
A circuit that contains pure resistance R ohms connected in series with a pure capacitor of capacitance C farads is known as RC Series Circuit. A sinusoidal voltage is applied and current I flow through the resistance (R) and the capacitance (C) of the circuit.
The RC Series circuit is shown in the figure below:

${V_R} = {\text{ voltage across the resistance R}}{\text{.}}$
${{\text{V}}_C} = {\text{ voltage across the capacitor C}}{\text{.}}$
${\text{V = total voltage across the RC series circuit}}{\text{.}}$
When components R and C are in series, the current must be the same (magnitude and phase) in
all parts of the circuit. The current through the resistor R is in phase with the voltage across R.
But the capacitive current is out of phase with the capacitor voltage. ${{\text{I}}_C}$ leads ${V_C}$ by ${90^ \circ }$. Therefore, the voltages across R and C are out of phase.

Note:
It should be remembered that an RC circuit is a circuit with both a resistor (R) and a capacitor (C). A capacitor is an electrical component used to store energy by separating electric charge on two opposing plates. And a capacitor can accumulate the energy and a resistor positioned in the series will switch the rate at which it charges or discharges. And the characteristic time dependence will be exponential.
