What is a resistor

A resistor is nothing magic. Take a long wire and measure the resistance, and you will realize that resistance is just a normal property of wires (except for superconductors). Some resistors are made up of just that. A long wire. But you can also find resistors made of other types of materials. Like this carbon … Continue reading What is a resistor

Functions of resistors CONTD. (TRANSISTOR BIASING)

TRANSISTOR BIASING One of the functions of a resistor is in biasing the base of a transistor. A transistor basically needs a small base voltage (>0.6) to make a large voltage flow through its collector/emitter terminals. But the base of a transistor is quite vulnerable to high currents, so a resistor is incorporated here to … Continue reading Functions of resistors CONTD. (TRANSISTOR BIASING)

Functions of Resistors in Electronic Circuits Explained

In an electronic circuit, the basic function of a resistor is to limit the current to a safe value so that the associated sophisticated parts can function properly. Read the article to understand what is the function of a resistor, through illustrated examples and formulas. Introduction Resistors come under passive electronic components and are extensively … Continue reading Functions of Resistors in Electronic Circuits Explained
