The load

Load refers to the connection in the circuit at the ends of the power electronic components. Should not be no load in a circuit, and the power supply directly to the poles are linked together, this connection is called a short circuit. Commonly used load resistance, and light bulbs can be consumed power of engine components. Not consumed power components, such as capacitance, can also pick up, but the situation is open circuit. Device that converts electrical energy into other forms of energy is called the load. Electric function converts electrical energy into mechanical energy, resistance can converts electrical energy into heat energy, light bulbs can converts electrical energy into heat and light, the speaker can converts electrical energy into sound energy. Motor, resistance, light bulbs, the speaker is called the load. Transistor for in front of the signal source, also can be regarded as a load. Is the most basic requirements for load impedance matching and can withstand the power.
