How Can I discharge a capacitor slowly | All About Circuits
2018年4月30日 · As your capacitor discharges through a fixed resistor it's voltage will drop, and current drop proportionately, not logarithmically, but not directly either. We know that lower current, obtained by either higher resistance or lower voltage, will result in a slower discharge of the capacitor. We obviously need values to make these calculations.
how to discharge a capacitor? - All About Circuits
2010年5月31日 · One way to discharge a capacitor is by shorting the two leads of the capacitor together. However, this should only be done with capacitors holding a very low voltage; otherwise, the current generated will be high and this can prove dangerous. The second, more safer way, to discharge a capacitor is through a load, usually a resistor.

How to discharge the capacitor? - All About Circuits
2015年10月21日 · In fact I used a 200K ohm resistor instead of 100K and a 1000uF capacitor and I had a delay time of about 3.5 minutes. The problem is when the main power off the 1000uF capacitor maintained its charge for long time and if the main power returned the circuit is ON immediately without any delay. How to discharge the capacitor? Thank you very much

2019年10月7日 · Just touch both leads of the capacitor at the same time with a pencil lead. The lead will conduct the energy and discharge the capacitor. Screwdrivers or other metal objects will get pitted. With a pencil lead - no problem. It offers some resistance, drains the cap fast, and is easily sacrificial.
How to discharge a capacitor at a given voltage?
2023年7月20日 · This is my small project. I am trying to discharge the capacitor at a given voltage, let's say, 3.2V. V3 will keep charging the capacitor, and the diode will prevent the capacitor from discharging. Before the cap reaches 3.2V, it will keep charging and never discharge (the diode blocks it from discharging).

I want to discharge capacitor in X seconds (Help)
2016年10月13日 · So it will take 5 seconds then to charge or discharge the 10uF capacitor with 100k resistor. Let's make it five times less than, to get it to actually discharge in 1 second after 5 time constants. 0.00001F / 5t = 0.00002F (50uF)

2024年9月19日 · If you discharge the capacitor through a resistor to ground, then all the energy in the capacitor between those two voltages is dissipated in the resistor. You are confusing the loss when charging a capacitor with loss in discharging it (which there isn't). The 50% loss is when you are charging the capacitor from a voltage source.
