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.

What resistor should I buy (More than 2kW peak power)
This is the graph of the current and the power in the resistor, as you can see there is a 2KW (4.5A) peak. But it's just in around 100ms, I wont repeat the pulse in 3 seconds or more. … What value should I use for the power rating of the resistor ? Thanks.
RMS in 2 seconds: ~20W
RMS in 3 seconds: ~13.5W …
