The power of household refrigerator is about P = 100W, while the working current is about I = 1a, and the working voltage is u = 220V. How to use p = UI to understand these data?

The power of household refrigerator is about P = 100W, while the working current is about I = 1a, and the working voltage is u = 220V. How to use p = UI to understand these data?

First of all, in AC circuit, P is not equal to UI! UI is called apparent power, which only indicates the occupancy of power, not the consumption. The actual consumption is active power P, which is less than UI. It is not only proportional to UI, but also proportional to power factor

The current of an electrical appliance is 1.1a. The electrical appliance may be a air conditioner B household refrigerator C TV D radio

B household refrigerator

Current knowledge of Junior Three: the concept of 1a, such as what electrical current is 1A?

Simple electric phenomenon circuit, charge, also known as electricity, is an attribute of matter. ① there are only positive and negative charges. The same charge as the glass rod rubbed with silk is called positive charge, while the same charge as the rubber rod rubbed with fur is called negative charge
