百度试题 结果1 题目If a 240-volt AC motor draws a current of 5 amperes, what is the apparent power?相关知识点: 试题来源: 解析 答案:\( S = V \times I = 240 \times 5 = 1200 \) volt-amperes
Apparent power is a measure of alternating current (AC) power that is computed by multiplying the root-mean-square (rms) current by the root-mean-square voltage. In a direct current (DC) circuit, or in an AC circuit whoseimpedanceis a pureresistance, the voltage and current are inphase, ...
Apparent power is the combined power value obtained by allowing for the different values of current and voltage. To calculate...

1 power triangle : - real power supplied to the load is on the lower axis but, because not all loads are purely resistive, the apparent power may be larger. this is because (in a simple sinusoidal situation): - apparent power = v r m s × i r m s apparent...
Reactive power is also called "phantom power" because it is not apparent where it goes. It is general knowledge that reactive loads such as capacitors and inductors do not actually dissipate power in a sense that it is not used to power them, but measuring the voltage and current around the...

established and the agency cannot be held responsible for the actions of the individual. When such authority is established without the agency being aware of it, then the agency may also oppose action against it on the grounds that there was never a basis for that authority being apparent....
What is the power factor (PF) The power factor (PF) is the ratio between active and apparent power and can take on values between 1 and -1. The Power factor is an indication of the amount of active power that is present in the transmission line compared to the apparent power that co...
