If the RC value (Resistance × Capacitance) is small in a circuit, what happens to the charging of a capacitor?
Answer: It charges faster
Explanation
If the RC value is small in a circuit, the capacitor charges fastly.
RC time constant: The time constant in an RC circuit is represented by the product of resistance (R) and capacitance (C).
Charging speed: A smaller RC value means the capacitor charges faster.
Large RC value: Conversely, a large RC value indicates a slower charging process for the capacitor.
