6 FAQs about [Capacitor where the power supply is disconnected]

Why do we shunt capacitors when a power supply is turned off?

These power supplies were bypassed (filtered) with capacitors that could hold a charge for a very long time. It became a common practice to always shunt these capacitors with a large resistor (1 M-ohm, for example) to discharge the capacitors when the equipment was turned off.

What causes a capacitor to discharge?

All capacitors have leakage so we can imagine that we have a very high-resistance (mega ohm) resistor parallel to the capacitor. When the capacitor is disconnected, the voltage will be discharged via this imaginary resistor. This is what causes the gradual discharge.

What happens when a power supply is turned off?

When you turn the power supply off, the system voltage begins to decay towards ground. The charge stored in the capacitors goes towards the rest of the system (that is, to where the power supply is connected) and, essentially, keeps the system running for a very short time longer.

How to discharge a capacitor?

Thus, the basic steps of discharging a capacitor are as follows: Cut off the power supply to the capacitor completely to ensure your safety. Use a volt/ohm meter or a multimeter to determine the amount of voltage the capacitor stores. Make sure you get the accurate amount of volts.

What happens when a voltage is placed across a capacitor?

When a voltage is placed across the capacitor the potential cannot rise to the applied value instantaneously. As the charge on the terminals builds up to its final value it tends to repel the addition of further charge. (b) the resistance of the circuit through which it is being charged or is discharging.
