6 FAQs about [Configuration of capacitor discharge resistor]

What is a capacitor resistor?

It’s essentially a high-value resistor connected across the terminals of a capacitor or between the positive and negative voltage rails in a power supply circuit. This tool calculates the value of Resistance (Ω) required to discharge a capacitor in a specified amount of time.

What is the time constant in a RC discharging circuit?

As the capacitor discharges its current through the series resistor the stored energy inside the capacitor is extracted with the voltage Vc across the capacitor decaying to zero as shown below. As we saw in the previous tutorial, in a RC Discharging Circuit the time constant ( τ ) is still equal to the value of 63%.

How do you calculate capacitor discharge?

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:

Is a RC capacitor fully discharged?

Note that as the decaying curve for a RC discharging circuit is exponential, for all practical purposes, after five time constants the voltage across the capacitor’s plates is much less than 1% of its inital starting value, so the capacitor is considered to be fully discharged.

What is the voltage across a capacitor in a RC charging circuit?

We saw in the previous RC charging circuit that the voltage across the capacitor, C is equal to 0.5Vc at 0.7T with the steady state fully discharged value being finally reached at 5T. For a RC discharging circuit, the voltage across the capacitor ( VC ) as a function of time during the discharge period is defined as:

How does resistance affect a capacitor?

The rate at which a capacitor charges or discharges will depend on the resistance of the circuit. Resistance reduces the current which can flow through a circuit so the rate at which the charge flows will be reduced with a higher resistance. This means increasing the resistance will increase the time for the capacitor to charge or discharge.
