Types of Resistors
Resistors perform two basic functions in a circuit: they limit current flow and set voltage levels within a circuit. We have various kinds of resistors e.g. fixed resistors, variable resistors, digitally adjustable resistors, photoresistors, fusible resistors, etc. Generally, resistors can … Read more

Resistance and Resistivity
The resistance of an electrical conductor depends on 4 factors, namely: The length of the conductor The cross-sectional area of the conductor The type of material The temperature of the material The resistance, R, is directly proportional to length L … Read more
