You can connect a watt meter to the circuit or it can be done by calculation. By calculation use this formula, Watts = Amps x Volts.
Watts and horsepower are both units of power.
It depends entirely on the power factor of the load. If the power factor is unity (1), then the true power, in watts, will equal the apparent power in volt amperes. If the power factor is zero, then the true power, in watts, will be zero. This is because true power (watts) is equal to the apparent power (volt amperes) multiplied by the power factor.
More Watts equals more power. So once you have decided which is bigger, 10 or 12.5, that is the one with more power.
power in watts = voltage in volts x current in amps. or power in watts = current in amps x (resistance in ohms) squared i think what you meant was power in watts =(current in amps)squared x resistance in ohms
Wire sizing is based on the motors full load amperage. The amperage can be calculated but a voltage has to be stated. I = W/E. Amps = Watts/Volts. Restate the question with a voltage and an answer can be given.
the unit which are measured for power of lights are watts....
3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.
Volts x Amps = Watts On 120 V you can connect 1200 W...although you might want to leave some room.
300 watts
Power is measured in watts.

191 Watts can power an iPad charger.

For powering a load over 150 watts, you can connect the inverter directly into your car battery. This involves using a 4-guage power cable that draws directly from the positive battery terminal. Without an in-line fuse or circuit breaker, you could short circuit the process.
