If an RC Circuit is supplied with 24VDC and the circuit is in its third time constant how much voltage would be present across the capacitor?
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.
Time constant is an exponential function, in some kind of form of e(-T/t) where T is time and t is time constant. If you evaluate this for T=3 and t=1, you get about 0.05. This means that the voltage across the capacitor will reach 95% of its final value after three time constants.
Whether this is 95% of 24V or 5% of 24V depends on how the circuit is designed, but the most probable answer with the limited information given is about 23V.

What is RC in electrical?
R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.

Negative.
What happens to the current in a circuit as a capacitor charges?
What happens to the current in a circuit as a capacitor charges depends on the circuit. As a capacitor charges, the voltage drop across it increases. In a typical circuit with a constant voltage source and a resistor charging the capacitor, then the current in the circuit will decrease logarithmically over time as the capacitor charges, with the end result that the current is zero, and the voltage across the capacitor is the same as the voltage source.
When a capacitor is charged after 1 time constant the v across the capacitor is?
Depending on the circuit, 63% of the available voltage.
Is capacitor a part of integrated circuit?
A small capacitor can be part of an integrated circuit.
How does the behavior of a circuit change when a capacitor and resistor are connected in parallel?
When a capacitor and resistor are connected in parallel in a circuit, the behavior changes in that the capacitor stores and releases electrical energy while the resistor controls the flow of current. This combination can affect the overall impedance and time constant of the circuit, leading to changes in the voltage and current characteristics.

Why is capacitor leakage a problem in a RC timer circuit?
Because the timing is set by the time constant of a resistor and a capacitor. With R in ohms and C in Farads, the time-constant is RC in seconds. If the capacitor leaks the timing will be wrong.
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
When a capacitor is connected to a circuit, what happens to the current flow through the capacitor?
When a capacitor is connected to a circuit, the current flow through the capacitor initially increases and then decreases as the capacitor charges up.
What is the formula for calculating the resistance of a capacitor in an electrical circuit?
The formula for calculating the resistance of a capacitor in an electrical circuit is R 1 / (2 f C), where R is the resistance, f is the frequency of the circuit, and C is the capacitance of the capacitor.
