Alternating Current

Item Code: SJ264

Principle and Working:

An RC circuit is a circuit with both a resistor (R) and a capacitor (C). A capacitor can store energy, and a resistor placed in series with it will control the rate at which it charges or discharges. This produces a characteristic time dependence and a crucial parameter that describes a capacitor’s rate of charge and discharge:
TC = R X C
Where, TC = time constant of capacitor
R = resistance of circuit
C = capacitance of capacitor
... CAPACITOR CHARGING: The rate of charge and discharge of a capacitor in an RC circuit is described by the time constant (TC). The time constant is defined as the time it takes the voltage across the capacitor to reach 63.2% of the supply voltage (Vmax)
CAPACITOR DISCHARGING: If the capacitor were shorted to ground with a jumper wire, the voltage across the capacitor would decrease.
LCR module discusses the overall effect of L, C, and R when connected in series and supplied by an alternating voltage. In such arrangements, the current provided passes through all the elements of the circuit equally.
