What are the functions of resistors?
1. Current limiting: In order to make the current passing through the electrical appliance not exceed the rated value or the specified value required for actual work, so as to ensure the normal operation of the electrical appliance, a variable resistor can usually be connected in series in the circuit. When changing the magnitude of the resistance, the magnitude of the current also changes accordingly.
2. Shunt: When several electrical appliances with different rated currents need to be connected to the main circuit of the circuit at the same time, a resistor can be connected in parallel at both ends of the electrical appliance with a smaller rated current. The function of this resistor is to shunt.
3. Voltage division: Generally, the rated voltage value is marked on the electrical appliances. If the power supply is higher than the rated voltage of the electrical appliances, the electrical appliances cannot be directly connected to the power supply. In this case, one resistor can be connected in series to the electrical appliances. A resistor with a suitable resistance value allows it to share a part of the voltage, so that the electrical appliance can work at the rated voltage.
4. Convert electrical energy into internal energy: When the current passes through a resistor, all (or part) of the electrical energy will be converted into internal energy. The electrical appliance used to convert electrical energy into internal energy is called an electric heater. Such as electric soldering iron, electric stove, rice cooker, Heaters and more.
5. Resistor bias function: The bias circuit often has several components, one of which is an important resistor, and the resistance value is often adjusted so that the collector current is within the design specification. The resistor to be adjusted is the bias resistor.
6. Filtering effect of resistors: The filtering effect of resistors is generally composed of RC filter circuits with capacitors, which can be divided into low-pass and high-pass circuits.
