Wikipedia Meaning and Definition on 'Resistors'
A resistor is a two-terminal electronic component having a resistance (R) that produces a voltage (V) across its terminals that is proportional to the electric current (I) flowing through it in accordance with Ohm's law:
Resistors are elements of electrical networks and electronic circuits and are ubiquitous in most electronic equipment. Practical resistors can be made of various compounds and films, as well as resistance wire (wire made of a high-resistivity alloy, such as nickel-chrome).
The primary characteristics of a resistor are the resistance, the tolerance, the maximum working voltage and the power rating. Other characteristics include temperature coefficient, noise, and inductance. Less well-known is critical resistance, the value below which power dissipation limits the maximum permitted current, and above which the limit is applied voltage. Critical resistance is determined by the design, materials and dimensions of the resistor.[See more about Resistors at Dictionary 3.0 Encyclopedia]
