在交流电路中,有效功率与电流和电压的相位角有关。 3.2. 虚功率 (Reactive Power) 虚功率是指在交流电路中,由于电感和电容的存在,电流和电压之间产生的相位差所导致的功率。虚功率用符号 ( Q ) 表示,单位是乏(VAR)。 3.3. 视在功率 (Apparent Power) 视在功率是指电路中总的功率,包括有效功率和虚功率。视...
What is Electrical Power and How Can You Calculate it in Series and Parallel Circuits? Electrical power measures the rate of work represented in electrical circuits by the symbol “P” and the units of Watts (W). The total circuit power is additive for series, parallel, or any combination ...
How to Calculate Power Factor To calculate power factor, you need apower quality analyzeror power analyzer that measures both working power (kW) and apparent power (kVA). With this data, you can calculate the ratio of kW/kVA. Power Factor Formula The power factor formula can be expressed in...
