Discharging a Capacitor (Formula And Graphs)
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. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination…

How do capacitors work?
Who invented capacitors? Here''s a brief history of the key moments in capacitor history: 1672: Otto von Guericke (1602–1686) develops a "machine" that can build up static charges when you rub it. A …
SURGE PROTECTION CIRCUIT PRINCIPLE and DESIGN
Surge in general is a sudden increase in level or magnitude from a normal or standard value. In electricity, surge is often used to describe voltage transient, voltage surge or voltage spikes. Voltage surge or spike or transient is not a permanent event. It is occurring only within a short period of time but more than enough to destroy devices if …

Why We Use Y Capacitors on EMI Filters to Ground
Capacitance Values The capacitance values of Y capacitors are crucial in determining their effectiveness in filtering out high-frequency noise. However, these values are often limited by safety regulations to prevent dangerous leakage currents. Leakage Currents: Higher capacitance values could lead to larger leakage currents to the ground, …

Capacitive Voltage Transformers (CVT)
A Capacitive Voltage transformer works on Capacitor Voltage Divider principle. For better understanding, assume a simple circuit of CVT which is connected between a line of 400 kV and Earth. As the CVT is connected between the line and earth, therefore phase voltage (400/1.732 = 230 kV) will be applied.
