Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

For example if the power is 100 watts and the voltage is 50 volts, the current is 100 / 50, or 2 amps. Calculate the resistance, in Ohms, by dividing the voltage by the current. Ohms law states that voltage = current x resistance, so by rearranging the formula resistance = voltage / current.

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second.

The power is inversely proportional the resistance based on the equation P = (V^2)*R. The power is independent of the resistance and is constant for a fixed resistance regardless of voltage and current changes.

Calculate the maximum safe current that can pass through a 1.8KΩ resistor rated at 0.5 Watts. Again, as we know the resistors power rating and its resistance, we can now substitute these values into the standard power equation of: P = I2R.

The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

In physics, the relation between watt and volt can be written as- 1 watt = 1 ampere × 1 volt 1\;volt=\frac{1\;watt}{1\;ampere} Where, Watt is the measure of power. Volt is the measure of electric potential. Ampere is the measure of current.

kVA to watts calculation formula So watts are equal to 1000 times kilovolt-amps times the power factor.

Thus - 1 (Amp) x 1 (Volt) = 1 Watt. say any Electric Appliance (May be an Electric Heater) having power of 1 Kilo Watt (i.e. 1000 watt), at Supply Voltage of 230 Volts, will draw a current = 1000(Watt)/ 230(Volts) = 4.3 Amps (aprox.) 60 Hertz in 1 Watt!

Volt-amps to kW calculation formula So kilowatts are equal to volt-amps times the power factor divided by 1000.
