What is static and dynamic electricity?

Is current electricity Dynamic electricity? Current electricity is the form of electricity which makes all of our electronic gizmos possible. This form of electricity exists when charges are able to constantly flow. As opposed to static electricity where charges gather and remain at rest, current electricity is dynamic, charges are always on the move.

What does a Bypass Switch in a UPS System Do?

A UPS Inverter, connected to a battery bank, draws direct current (DC) and converts it to consistent alternating current (AC). If the UPS inverter fails, the static bypass switch detects the voltage drop and quickly switches to the grid''s AC power, ensuring uninterrupted power to the connected loads.
