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...
Ohm's Law is the linear proportionality between current and voltage that occurs for most conductors of electricity. A graph of voltage against current is a straight line. The gradient is the resistance. Practitioners rarely speak ofpotential difference, when electrical voltage (drop) is meant. VIR...
Is voltage constant in a parallel circuit? (a) Find the amplitude of the wave given from the graph of a wave that has joules as the y-axis and time on the x-axis. (b) Find the wavelength given from the graph below. Explain the relationship between amperage, voltage...
