The resistance, the precision of that value, the thermal or electrical environment, the style of indicating these values. There are wire-wound resistors, cracked carbon resistors, carbon resistors and so on.
Yes, a 47 ohm resistor can be used in place of a 47E resistor, as "47E" typically denotes a 47 ohm resistor where "E" represents ohms in certain notations. However, ensure that both resistors have similar power ratings and tolerances for optimal performance in your circuit. Always double-check the specifications to ensure compatibility with your application.
If a resistor does not have a gold or silver band, it typically indicates that the resistor does not have a specified tolerance, suggesting it could be either a low-precision resistor or designed for specific applications where tolerance is not critical. Alternatively, it may also be a non-standard resistor where the color coding is not applicable. In such cases, one might need to refer to the manufacturer's specifications or use a multimeter to measure the resistance value directly.
Yes, the 1978 Honda XL250S requires a 3.61-ohm resistor connected to the low beam circuit. This resistor helps to regulate the current and protect the headlight bulb from overheating or burning out. It's important to ensure that the electrical connections are secure and that the resistor is of the correct rating for optimal performance. Always refer to the service manual for specific wiring diagrams and specifications.
To test a Negative Temperature Coefficient (NTC) resistor, use a multimeter to measure its resistance at room temperature. Then, immerse the resistor in a controlled heat source (like a water bath) and monitor the resistance as the temperature increases; it should decrease as temperature rises. Alternatively, you can use a simple circuit with a known voltage and measure the current to calculate resistance at different temperatures. Comparing these values to the NTC resistor's specifications will confirm its functionality.
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).

The ohms tells you the resistance; the wattage tells you how much heat energy it can handle. Not that any resistor ever lived up to its specifications -- I always needed some type of heat sink. Bottom line -- yes.

Yes, you can use an RC12YC instead of a QC12YC spark plug, as both have similar specifications. However, it's important to check the manufacturer's recommendations for your specific engine, as the RC12YC is typically a resistor plug while the QC12YC is a non-resistor plug. Using a resistor plug may affect ignition performance in some applications, so ensure compatibility with your engine's requirements.
To test the blower motor resistor on a 2004 Nissan Armada with four wires, first, ensure the vehicle is off and disconnect the resistor's electrical connector. Use a multimeter to measure the resistance across the terminals; you should find varying resistance values between the terminals, indicating that the resistor is functioning. If there's no continuity or the resistance is significantly off from specifications, the resistor is likely faulty and should be replaced. Always refer to the vehicle's service manual for specific resistance values and further troubleshooting steps.
yes, a variable resistor
To run a 12V LED from a 24V supply, you can use a resistor or a DC-DC buck converter. If using a resistor, calculate the appropriate resistance value to limit the current to the LED's specifications, ensuring it can handle the excess voltage drop. A buck converter is more efficient, converting the higher voltage down to 12V without significant power loss. Always ensure that the current drawn does not exceed the LED's rated specifications for safe operation.
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.
