the formulas for calculating electrical energy is

E (dissipated in a resistor R)=(I^2)*R*t=VI=(V^2)/R

where V is voltage across resistor ,I is current,t is time.

or if there is a function of time the equation becomes

E= integral from 0 to t (i(t)^2*R) dt

it is the integral of the power dissipated for the time in question.

How do electric companies calculate electric energy used?

Electric companies calculate electric energy usage by multiplying the power consumption (in kilowatts) by the time the power is consumed (in hours). This formula is expressed as kWh (kilowatt-hour) and is how customers are billed for their electricity usage.


What is the kilowatt power draw of an electric furnace that measures 20 amps and 240 volts at it's power circuit?

The kilowatt power draw of the electric furnace can be calculated using the formula: Power (kW) = Current (A) x Voltage (V) / 1000. Plugging in the values (20 A and 240 V) into the formula, we get: Power = 20 A x 240 V / 1000 = 4.8 kW. Therefore, the electric furnace has a power draw of 4.8 kilowatts.
