Question

How does RC circuit work.

Answer 1

Hint :All electric or electronic circuits or structures be 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.

Complete Step By Step Answer:
The resultant time consistent of any digital circuit or system will particularly rely on the reactive components either capacitive or inductive connected to it and is a dimension of the response time with devices of, Tau – τ.
while a growing DC voltage is applied to a discharged capacitor, the capacitor draws a charging modern and “costs up”, and while the voltage is reduced, the capacitor discharges in the opposite path. Due to the fact capacitors are able to save electrical strength they act like small batteries and can keep or release the electricity as required.
The price at the plates of the capacitor is given as Q = CV. This charging (storage) and discharging (launch) of the strength of a capacitor is by no means immediately however takes a positive quantity of time to arise with the time taken for the capacitor to fee or discharge to within a positive percentage of its maximum deliver fee being called its Time steady (τ).
If a resistor is attached in collection with the capacitor forming an RC circuit, the capacitor will rate up regularly thru the resistor till the voltage throughout the capacitor reaches that of the delivered voltage. The time is also known as the brief reaction, required for the capacitor to completely price is equal to approximately five-time constants or 5T.

Note :
An RC circuit is a circuit with both a resistor (R) and a capacitor (C). ... A capacitor can shop strength and a resistor placed in series with it'll manipulate the charge at which it prices or discharges. This produces a characteristic time dependence that turns out to be exponential.
