The load refers to power and current through wires, cables, and electrical equipment (transformers, circuit breakers, etc.). The load is not a value, but a variable value that varies over time. Not all electrical equipment is running at the same time, even if it is running, they can't all reach the rated capacity. In the design, the capacity of each electrical device is simply added as a selection wire, the cable cross section and the electrical equipment capacity are not scientific.

The general meeting causes the equipment underload, which will lead to overload, causing insulation damage, line loss Increased, affecting the safety operation of wires, cables, or electrical equipment, which will cause fire accidents. In order to avoid this happening, use a hypothetical load, ie the calculated load, to indicate the total load of the system, and select the wire, the device, etc., the device, etc.

The load refers to the electronic component connected to both ends of the power supply in the circuit. The two poles of the power supply should not be directly connected to the circuit without the load, which is called a short circuit. Common loads include components that consume electric power such as resistors, engines, and bulbs. Converting electrical energy to other forms of energy. The motor converts electrical energy into mechanical energy, and the resistance converts electrical energy into thermal energy, and the bulb is converted to heat energy, and the speaker is converted into sound energy. Motors, resistors, bulbs, speakers, etc. are called load. Crystal triodes can also be considered as a load of the front signal source. The most basic requirements for load are impedance matching and power it can withstand.
