How fast electrical energy changes into other types of energy
Watts (W)
One joule of energy transfers every second
P=IVP = IVP=IV
When you know current and voltage
P=I2RP = I^2RP=I2R
When you know current and resistance
P=EtP = \frac{E}{t}P=tE
When you know energy transferred over a certain time
Amps (A)
Volts (V)
Ohms (Ω)
Power of 1 watt
Current multiplied by itself
