Resistors

DEFINITION: A resistor is an electrical component that limits or regulatesthe flow of electrical current in an electronic circuit.Resistors can also be used to provide a specific voltage for an active device such as a transistor. All other factors being equal, in a direct-current (DC) circuit, thecurrent through a resistor is inversely proportional to its resistance, and directly proportional to thevoltage across  …

In alternating-current (AC)circuits, this rule also applies as long as the resistor does not contain inductance orcapacitance. Resistors can be fabricated in a variety of ways. The most commontype in electronic devices and systems is the carbon-composition resistor. Fine granulated carbon (graphite) is mixed with clay and hardened. Theresistance depends on the proportion of carbon to clay; the higher this ratio, the lowerthe resistance. Another type of resistor is made from winding Nichrome or similar wire onan insulating form. This component, called a wirewound …
