Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt (one joule per second). Use this tag where power is a primary concern for the design under discussion. Use the "low-power" tag when that applies.

Limiting power in a circuit efficiently?
Dimmers cut off sine wave at certain level leaving only part of power going through.
Variable transformer is another way.
It all depends on the load. Usually load is what defines the power. … In today's electronics one way is to efficiently rectify, get nice DC with a cool power factor, then create whatever AC you want. …

Load balancing across multiple power supplies with different voltages
Rating - prepare for the full power. If one of the supplies goes down, even during debug you don't want the rest to burn.
Not sure about standards, but I am sure I saw something similar with Victron. …

Meaning of resistor power rating
You must be well below maximum power.
Besides, I guess you have your battery in an enclosure; you probably wouldn't want to emit too much heat there. … It is not related to resistor absolute maximum power, but is an important consideration also. …

How does a power plant's increased output translate to the Volts, Amps and Watts on the powe...
A power plant increases amount of fuel burning, which is also power. It increases power when it sort of lags a little bit in terms of frequency. … So the thing that changes the most to compensate for added power is current, which is tightly related to torque applied by steam on the turbine. …
