Electronic components > 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 ...

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 ...

color codes
Electronic components; Resistors

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 ...

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 ...

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 ...

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 ...

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 ...
