There are various forms of resistors used for electronic circuits. You can divide it in mainly two basic types:
Some other types or resistors are as following:
combined
Same as any other kind of resistor, they're used to control voltages and currents in electric circuits.
A special kind of resistor can oppose the flow of an electrical current.
yes, a variable resistor
If a blower motor resister is bad the fan won't work at all or will only work on certain speeds. And you will see on the resistor a missing link where it burnt out kind of like in a light bulb
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
POWER=VI. V=voltage I= current
I = E / RIf the voltage across the resistor is 90 volts, and the resistance of the resistoris 9 ohms, then the current through the resistor is90/9 = 10 Amperes.Don't try this at home!The power dissipated by the resistor is E2/R = (90)2/9 = 900 watts. That's comparable to the power (heat) dissipated by a small toaster. A common composition resistor will get hot and possibly explode if it's asked to dissipate that kind of power.
The Cable is the Resistor ! Its a Resistor-Cable ! Greets from the Lake of Constance/Germany !
