Visit BYJU’S to understand the relation between Resistance and Length along with Resistance and Length formula, units, definition, problems, and resistivity formula.
If there is AC, look also at the power factorPF= cosφandφ= power factor angle (phase angle) between voltage and amperage. ElectricEnergyisE=P×t− measured in watt-hours, or also in kWh. 1J = 1N×m = 1W×s Power Formula 2– Mechanical power equation:PowerP=E⁄twhere powerPis...
