Formula The formula used by this calculator to determine the DC electrical power generated from the voltage and current is: P = V · I Symbols P = Electrical power (DC) V = Voltage (DC) I = Current (DC) Voltage (V) This is the DC voltage or electrical potential difference applied to...
from the formula of power, we can say that power is the product of voltage and current. from the definition, we can say that the current is inversely proportional to the voltage when power is constant. therefore, when the voltage is increased, power will increase proportionally provided that ...

In this case, power used by the kettle is RI^2 = 2211W (with R=24 ohms). Using the same formula with R=0.5 ohms gives an upper bound of 46W for power lost in the electrical grid. Actual losses will be lower, as the impedance I measured at my electrical soc...
To calculate the power dissipated by each light bulb, we insert the measured values into the formula given above. If we want to know the power dissipated by the entire circuit, we add up the power dissipation of the individual components: Or, we can multiply the current supplied fr...
