Resistors

wirewound

Electronic components; Resistors

A Resistor made up of resistance wire, wound on an insulated form. A wirewound resistor may be variable or fixed. Wire-wound resistors are normally used as power resistors. Types of wirewound ...

Ohm's law

Electronic components; Resistors

The current in an electrical circuit is directly proportional to the electromotive force in the circuit. The most common form of the law is E = IR, where E is the electromotive force or voltage ...

Resistor color codes (used on thru-hole devices) indicate the devices value, tolerance and in some cases its failure rate. In some cases, 1 percent resistors may use a three digit or four digit code ...

inductive resistor

Electronic components; Resistors

A resistor having a higher than normal inductance. In many cases these will be wirewound types. Normally inductive resistors are not used in high frequency circuits because of their high inductance. ...

trimmer

Electronic components; Resistors

A variable resistor. Designed for less then frequent changes (occasional)~ a trim pot on a PCB to finalize a circuit resistance. A variable resistor used to trim resistance in a circuit, normally ...

voltage rating

Electronic components; Resistors

Resistors shall have a rated direct current (dc) continuous working voltage or an approximate sine-wave root-mean-square (rms) alternating current (ac) continuous working voltage at commercial-line ...

power resistor

Electronic components; Resistors

A resistor with a power dissipation higher than a quarter watt (0.25w), or half watt (0.5w). However the military classifies power resistors as resistors having power a dissipation above 3 watts. The ...
