Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
The first 3 band on a resistor indicate the value of that resistor.
A resistor.
LDR refers to Light Dependent Resistor.
A resistor is bi-directional meaning current can flow in either direction. Current flows from positive to negative.
The resistance value of a resistor indicates how well it can insulate against the flow of electric current. A 24-ohm resistor has a higher resistance compared to a 6-ohm resistor, meaning it is better at restricting current flow and thus acts as a better insulator. Therefore, the 24-ohm resistor is the better insulator.
"Load resistor" is a discriptor, not a value. Any resistor can be a load resistor if it is the proper value and power for your application. So if you want a load resistor by itself, that makes no sense. A load resistor is a resistor selected for a specific purpose. For example, it you want to put a load on an audio amplifier made to drive an 8 ohm speaker to 50 watts, then your load resistor would be a 8 ohm 50 watt resistor. If you want a load resistor to terminate a 50 ohm line, you would need a 50 ohm resistor, although in this case, you probably want one that is part of a co-ax connector. A load resistor for an op-amp output is typically 2k, since most op-amps are rated for 10 volts at 5 mA. Etc, etc.
yes, a variable resistor
It is not a resistor, but not to say it's a good conductor. Although it lacks the metallic bonding that makes Cu such a good conductor, the sheets of graphite have hybridized sp2 orbitals, meaning there are long rows of p orbitals that can share electrons across the sheet, meaning it can conduct electricity. It has a resistivity of ~20uOhm meters, whereas as Cu has a resistivity of ~17nOhm meters.
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.
Otis F. Boykin invented the wire precision resistor and the electrical resistor.
on electronic components, of course, can not be made absolutely perfect. so there must be imperfections in the making, it is called tolerance. for ex: 100ohm resistor ,a tolerance of 5%, meaning the resistance between 95-105ohm (100ohm * + / -5%). not fit 100ohm.
The Cable is the Resistor ! Its a Resistor-Cable ! Greets from the Lake of Constance/Germany !
