Answer: the current through the closed path. 2, what is power? Answer: electrical equipment (load) power consumption during operation. 3, what is the reactive power? Answer: the load contains inductors or capacitors at work in order to establish a working magnetic field or electric field, a part of energy in the power supply and the load back and forth between the exchange, the power consumption is not supported. 4, what is the apparent power? Answer: the power or load of working voltage and working current will be multiplied by the apparent power. 5, what is the power factor? Answer: the load voltage and current phase difference of angle cosine. It is equal to the size of the active power and the ratio of apparent power. 6, what is called line voltage? Answer: in the three-phase AC circuit, and the line between the end (i.e. the voltage between the line). 7, what is the phase voltage? Answer: in the three-phase AC circuit, line (i.e., FireWire) and line (zero line) between the voltage. 8, what is the linear resistance? Answer: refers to the voltage at both ends of the resistor element and is proportional to the current through it, the resistance value of R for constant resistance element. 9, what is the instantaneous power? Answer: for AC circuit, the transient current and voltage values will change with time, so the power The instantaneous value also varies with time. 10, what is the inductance? Answer: when the alternating current through the coil inductance, resistance and electromotive force of the coil to prevent current change. The 11, what is the capacitance? Answer: when the alter
