Google 'Ohms Law'
AnswerOhm's Law has nothing whatsoever to do with power.
The fundamental equation for power in a d.c. system is: P = E I (where P = power, E = supply voltage, and I = load current). From this equation, two others can be derived: P = I2R and P = E2/R, where R = resistance.
For a.c. systems, the fundamental equation must be multiplied by the load's power factor (cosine of the phase angle).
Power (watts) is voltage times current.
Voltage is joules per coulomb. Current is coulombs per second. Multiply them together, and you get joules per second, which is also known as watts. Integrate that over time, and you get watt-seconds, or just plain joules. We also use the term kilowatt-hours; that is simply 3.6 million joules.
Of course, if the load is reactive, which it often is, the phase angle between voltage and current is non-zero, making apparent power (watts) not the same as true power (volt-amps, or VA). The ratio of watts over VA is Power Factor, and that is the cosine of the phase angle.

Energy = power x time. If power is in watts, and time in seconds, energy will be in joules.
electrical energy (in kWh) = electric power (in kWh) X time (in hours) E=Pt
Wattage = voltage times amperage. That's for DC. For AC there is a power factor PF = cos phi you have do multiply with.AnswerThe above answer suggests that power ('wattage') is an electrical unit, which it is not. In fact, power is defined as the rate of doing work, so the basic equation is work divided by time.
Power hasn't a chemical equation.
Electrical motors convert electrical energy into mechanical energy.
There are no amps in a voltage because they are quite different electrical units. They are related by the 'power equation' which is: watts = amps times volts
2 to the power of 4 is an expression, it is not an equation.
You are confusing electrical potential (Volts) and power (Watts). The equation for power (watts) is P = VI where V is volts (a measure of electrical "pressure") and I is current in amperes (the rate of flow of electricity). If the system is 120V and the power used is 600W then the current used is 5A. If the system is 240V and the power used is 600W then the current used is 2.5A.
