Power and Energy - Demonstrated

With the defaults set you can see that a 120 volt appliance with a Power (Rate) of 1,000 Watts running for 1 Hour will use 1 kWhs of energy. Click Calculate Energy button below to see this.

Experiment with various Power and Time settings and note the Energy results. Time can be set to: Hours, Minutes, Seconds, or in combination of the three. Volts is defaulted to 120 Volts (US), but can be changed to see different results.

Review

Above are three tables: POWER, TIME, and ENERGY. Note that as Watts goes up: Amps (Current) goes up, Joules goes up, and Ohms (Resistance) goes down.

POWER is the RATE a which energy is converted or consumed. TIME table is the amount of time an appliance (load) is ON, and ENERGY is the AMOUNT of work done.

Joules, Amps, and Ohms will be expanded on soon.
