How to Discharge a Capacitor? Using Bleeder Resistor, Screwdriver, Lamp

Why Do We Need to Discharge Capacitors? As mentioned before, capacitors store electric charge and they can hold the charge even if we remove the main power supply. If you accidentally touch the leads of the capacitor after disconnecting the power supply thinking that no power supply; no problem, then you can get an electric …

Understanding Mercury Vapor Lights & Ballasts

A 40 watt lamp used 40 watts for the tube, and the ballast had about 10 watts of loss, so the fixture as a whole used 50 watts. It would be fair to assume the ballast for a 100 watt mercury vapor lamp would waste ~ 20 watts .

OverviewPrinciples of operationHistoryPhosphors and the spectrum of emitted lightApplicationsComparison to incandescent lampsDisadvantagesLamp sizes and designations

The fundamental mechanism for the conversion of electrical energy to light is the emission of a photon when an electron in a mercury atom falls from an excited state into a lower energy level. Electrons flowing in the arc collide with the mercury atoms. If the incident electron has enough kinetic energy, it transfers energy to the atom''s outer electron, causing that electron to temporarily jump …

How to Discharge a Capacitor

It is important to note that the best rating for low-voltage capacitors is a 5-watt 2kΩ resistor, while the best for high-voltage capacitors is a 5-watt 20kΩ resistor. The idea here is that the higher the resistance, the slower the transfer of energy from the capacitor, and the safer the discharge process is.
