In electrical and electronic circuits, the resistor is a passive circuit component that is used to introduce electrical resistance in the flow of electric current through the circuit. Therefore, the primary function of a resistor is to control the amount of current through a circuit. Here is the basic tutorial about introduction to resistors - resistance measurement, symbols, working and its characteristics along with examples. The resistor circuit symbols are usually enhanced with both a resistance value and a name. The value, displayed in ohms, is obviously critical for both evaluating and actually constructing the circuit. A resistor is a passive component that implements electrical resistance in a circuit. Learn about its symbols, values, power dissipation, and applications in electronics and electrical networks.
