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).
The first 3 band on a resistor indicate the value of that resistor.
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.
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.
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.
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
The Cable is the Resistor ! Its a Resistor-Cable ! Greets from the Lake of Constance/Germany !
Where would you find a material which is a resistor? You can find a resistor material in Europe
