In a transient response of an RC circuit, what is the behavior of the current as the capacitor charges?

Step 1: Understand that an RC circuit consists of a resistor (R) and a capacitor (C) connected in series.
Step 2: When the circuit is powered, the capacitor starts to charge up.
Step 3: Initially, when the capacitor is uncharged, the current is at its maximum value.
Step 4: As the capacitor charges, it stores electrical energy, which causes the current to decrease.
Step 5: The decrease in current is not linear; it follows an exponential pattern.
Step 6: Eventually, the capacitor becomes fully charged, and the current approaches zero.

Transient Response in RC Circuits – The behavior of current and voltage in an RC circuit during the charging and discharging phases.
Exponential Decay – The mathematical description of how the current decreases over time as the capacitor charges.
