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 be broadly categorized as: Fixed Resistors Fixed resistors are those whose value cannot be changed…

Key Facts about Resistors, Resistor Colour Codes and Resistor Tolerance
Resistors perform two basic functions in electronics: These two Resistor features of current limiting and voltage setting are implemented in various ways in electronics as listed below: The figure below shows how a resistor is used as a current limiter: The figure below demonstrates how a resistor is used to create a voltage divider capable…
