That is a measureof the extent that the current waveform matches the voltage waveform. The ideal power factor is 1, which means that the current is everywhere proportional to the voltage, such as would be the case with a purely resistive load. Real loads have reactive (capacitive or inductive) components, or drawcurrent in pulses or erratically. You have 2 phases, and a current per phase of 0.33A, so your total current shouldn't exceed 0.66A per motor.. An amp-hour is a measurement of current (in amps) flowing over a period (an hour). ... So, if house electric is costing 15 cents a kilowatt, and one knows the amp draw of an appliance, how to you calculate the cost/hour to run that appliance?. Rv 6 volt battery wiring.
Sorry - but assuming you mean household line/mains current (ie 120/230V) then anybody who needs to ask is probably not safe dealing with potentially lethal voltages. I have a situation with a very small indicator lamp. The voltage is 5.4Vac. One lamp is burned out (I want to replace both). With a common multimeter in series with the good bulb. Any imbalance current comes from leakage from the conductors to ground or elsewhere. To measure this current, a leakage clamp meter should be able to read less than 0.1 mA. For example, taking a measurement on a 240 V ac circuit with all loads disconnected might result in a value of 0.02 A (20 mA) leakage. Mar 26, 2016 · Switch the multimeter selector to measure DC current in milliamps (mA). Then break the connection between the resistor and LED.
