Question
Consider the first-order RC series circuit and connect the 10 V DC source to the input of the RC circuit, then, what will be the amount of current flowing through the capacitor at t = ∞?
Solution
To determine the amount of current flowing through the capacitor at t = ∞ in the first-order RC series circuit, we need to analyze the behavior of the circuit over time.
-
First, let's understand the components of the circuit. The RC series circuit consists of a resistor (R) and a capacitor (C) connected in series, with a 10 V DC source connected to the input.
-
At t = 0, when the circuit is initially energized, the capacitor is uncharged. As a result, the current flowing through the circuit is initially at its maximum value.
-
As time progresses, the capacitor starts to charge up. The charging process is exponential in nature, and the rate of charging is determined by the time constant (τ) of the circuit, which is equal to the product of the resistance (R) and the capacitance (C).
-
As t approaches infinity, the capacitor becomes fully charged. At this point, the current flowing through the capacitor decreases to zero. This is because a fully charged capacitor acts as an open circuit, blocking the flow of current.
-
Therefore, at t = ∞, the amount of current flowing through the capacitor in the RC series circuit will be zero.
In summary, at t = ∞, the current flowing through the capacitor in the first-order RC series circuit will be zero.
