AI Customer ServiceWhen a capacitor is discharged, the current will be highest at the start. This will gradually decrease until reaching 0, when the current reaches zero, the capacitor is fully discharged as there is no charge stored across it. The rate of decrease of the potential difference and the charge will again be proportional to the value of the current.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
Figure 8.4.1: The capacitors on the circuit board for an electronic device follow a labeling convention that identifies each one with a code that begins with the letter “C.” The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates.
This stored charge is directly related to the capacitor's capacitance and the voltage applied across its plates, allowing it to temporarily hold electrical energy for later use. The relationship between charge, capacitance, and voltage is fundamental to understanding how capacitors function in circuits.
E = 1/2 cv²: The equation $$e = \frac {1} {2} cv^ {2}$$ represents the energy stored in a capacitor, where 'e' is the energy in joules, 'c' is the capacitance in farads, and 'v' is the voltage across the capacitor in volts. This relationship shows how the energy stored in a capacitor depends on both its capacitance and the voltage applied.
For the equation of capacitor discharge, we put in the time constant, and then substitute x for Q, V or I: Where: is charge/pd/current at time t is charge/pd/current at start is capacitance and is the resistance When the time, t, is equal to the time constant the equation for charge becomes:
