The choice and function of resistance in circuit design
Summary
Resistor is one of the most commonly used devices in electronic products. Basically, as long as it is an electronic product, there will be resistance inside. Resistors can be used as voltage dividers, shunts and load resistors in circuits; together with capacitors, they can form filters and delay circuits; used as sampling resistors in power circuits or control circuits; used in semiconductor tube circuits Bias resistors determine the operating point; use special resistors such as varistors and thermistors to prevent surge voltage, suppress inrush current, and achieve over-temperature protection, and so on. Resistor is the most common device, and it is also an indispensable device in the circuit. Choosing a good resistor is very important to the stable operation and reliability of the product.
