Capacitor Discharge Graphs | CIE A Level Physics

As a capacitor discharges, the current, p.d. and charge all decrease exponentially. This means the rate at which the current, p.d. or charge decreases is proportional to the amount of current, p.d or charge it has left;

Is the capacitor discharge current very large

6 FAQs about [Is the capacitor discharge current very large ]

What is a capacitor discharge graph?

Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.

What happens when a capacitor is fully discharged?

As charge flows from one plate to the other through the resistor the charge is neutralised and so the current falls and the rate of decrease of potential difference also falls. Eventually the charge on the plates is zero and the current and potential difference are also zero - the capacitor is fully discharged.

Why does a smaller capacitance cause a faster discharge?

Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can't hold as much charge, and thus, the lower V C at the end. These are all the variables explained, which appear in the capacitor discharge equation.

How much voltage does a capacitor discharge?

After 2 time constants, the capacitor discharges 86.3% of the supply voltage. After 3 time constants, the capacitor discharges 94.93% of the supply voltage. After 4 time constants, a capacitor discharges 98.12% of the supply voltage. After 5 time constants, the capacitor discharges 99.3% of the supply voltage.

What happens when a capacitor reaches a maximum voltage?

Finally, this will result in the voltage at peak current equal to the initial voltage. At this point in time, the capacitor has reached its maximum current value. Now using the total electric charge equation, the amount of charge lost during the ramp up time can be found.

What is discharging a capacitor?

Discharging a Capacitor Definition: Discharging a capacitor is defined as releasing the stored electrical charge within the capacitor. Circuit Setup: A charged capacitor is connected in series with a resistor, and the circuit is short-circuited by a switch to start discharging.
