16. State the equation for charge in a circuit where a capacitor is discharging in terms of $R$ and $C$ . $\qquad$
17. Define the term time constant when referring to capacitors.

Studdy Solution
The time constant $\tau$ for a capacitor in a circuit is defined as:
$\tau = RC$
It represents the time required for the charge, current, or potential difference to decrease to approximately 36.8% of its initial value during discharging, or to increase to approximately 63.2% of its final value during charging.
