Inductorsdo not have a stable “resistance” as conductors do. However, there is a definite mathematical relationship between voltage and current for an inductor that you can think of asOhm's lawfor an inductor: v=Ldidtv=Ldidt Where:
where powerPis in watts, voltageVis in volts and currentIis in amperes (DC). 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 ...
V=IR We can express Ohm’s Law mathematically using the equation: Voltage = Current x Resistance V=IR Voltage measured in Volts (V) Current measured in Amps (A) Resistance measured in Ohms () Resistance for a bulb If you have a filament bulb and it has a current of 20A running th...
voltage at a level sufficiently high to maintain a condition at or beyond the threshold of glow discharge at the region of the workpiece upon which the jet of the electrolyte impinges, said level not being so high as to permit sparking to occur directly between the electrode and the workpiece...
b. When a voltage of 120 V is impressed across an electric heater, a current of 10.0 amps will flow through the heater if the resistance is ___ Ω. c. A flashlight that is powered by 3 Volts and uses a bulb with a resistance of 60 Ω will have a current of ___ Amps. See Ans...
