Introduction to Resistors
Resistors are generally called resistors directly in daily life. It is a current limiting component. After connecting the resistor in the circuit, the resistance value of the resistor is fixed, usually two pins, which can limit the current through the branch connected to it. A resistor whose resistance cannot be changed is called a fixed resistor. Variable resistance is called potentiometer or variable resistor. An ideal resistor is linear, that is, the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Variable resistor for voltage divider. On the exposed resistor body, press one or two removable metal contacts. The contact position determines the resistance between either end of the resistor body and the contact. The terminal voltage and current have a definite functional relationship, and the two-terminal device that reflects the ability to convert electrical energy into other forms is represented by the letter R, and the unit is ohms.
Actual devices such as light bulbs, heating wires, resistors, etc. can be represented as resistor elements. The resistance value of a resistive element is generally related to temperature, material, length, and cross-sectional area. The physical quantity that measures the resistance to temperature is the temperature coefficient, which is defined as the percentage of the resistance value that changes when the temperature increases by 1°C. The main physical feature of a resistor is to convert electrical energy into thermal energy. It can also be said that it is an energy-consuming element, and the current passes through it to generate internal energy. Resistors usually play the role of voltage divider and current shunt in the circuit. For signals, both AC and DC signals can pass through resistors.
