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.
The formula you are looking for is W = I x E.
32 countries in the world are using nuclear electric power.
The formula you are looking for is W = E(squared)/R, W = Voltage (squared) divided by Resistance.
It generates electric power from other sources of primary energy.
Electricity doesn't give power. Power is simply the rate at which work is done in an electric circuit.
The flow of electrons to create energy.
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.
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.
Electric power
There are many advantages of electric power over gas power. Electric power does not require fuel to work and electric can be a cleaner source of power.
why is electric power good
The dimensional formula of electric current is [I] = [A], where I represents current and A represents ampere.
The name says it "electric" power.
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
Hydro Electric Power
The electric current is given by: I = V/R
the formula for power is work/time.
