Description
The relationship between the terminal voltage and the current has a definite function, which reflects the power conversion into other forms of the two-terminal device, with the letter R to represent the unit ohm Ω. Actual devices such as light bulbs, electric wires, resistors, etc. can be expressed as resistor elements.
The magnitude of the resistance of the resistive element is generally related to the temperature, material, length, and cross-sectional area. The physical quantity that measures the magnitude of the resistance by the temperature is the temperature coefficient, which is defined as the percentage change in resistance when the temperature rises by 1 ° C. The main physical characteristic of the resistance is that the electric energy is the heat energy, and it can be said that it is a kind of energy consuming element, and the electric current passes through it to produce the internal energy. Resistance in the circuit is usually the role of partial pressure, shunt. For the signal, the AC and DC signals can pass through the resistor.
Made of resistive material, there is a certain form of structure, can be used in the circuit to limit the current through the role of the two-terminal electronic components. Resistance can not be changed as a fixed resistor. Resistance variable called the potentiometer or variable resistor. The ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Some special resistors, such as thermistors, varistors and sensitive components, have a non-linear relationship between voltage and current. Resistors are the most widely used components in electronic circuits, and are typically different in terms of power and resistance for circuit designers. Resistors are mainly used in the circuit to regulate and stabilize the current and voltage, can be used as a shunt and voltage divider, but also for the circuit to match the load. According to the circuit requirements, but also for the negative feedback circuit or positive feedback, voltage - current conversion, input overload voltage or current protection components, but also the composition of the RC circuit as oscillation, filtering, bypass, differential, integral and time constant Components and so on.
