☑ How To Test Resistors On A Motherboard

Resistors are electrical components that limit the flow of electrical current in an electronic circuit. Sipski today i am going to show you how i remove micro resisters and capacitors from a motherboard circuit boar.

The first 2 or 3 represent the significant digits and the last indicates the number of 0s that should follow.

How to test resistors on a motherboard. The exact method required to update the bios varies by motherboard manufacturer and model. Compare the letter at the end of the code with the tolerance it represents. Applying the wrong bios update may make the motherboard unusable short of returning it to the factory for repair.

How to check resistors with meter how to test value of carbon color resistors voltmeter multimeter measure a bad resistor in a tv power supply color code for resistor colour bands are at. Read the 3 or 4 numbers on the resistor. Resistors regulate the amount of current flowing in an electronic circuit.

How to test resistors. Some motherboards are updated simply by copying the updated bios file to a floppy disk or cd and booting from it. Keep the leads jumped for several seconds to fully discharge any stored power.

Turn the resistor so that this band is to your right. Discharge any capacitors in the circuit by touching the leads of a spare high wattage resistor to the leads of the capacitors. Touch one multimeter probe to each lead of the resistor.

For example a resistor reading 1252 indicates a rating of 12500 ohms or 125 kilo ohms. Resistors present a resistance or impedance to the electrical circuit and reduce the amount of current that is allowed to flow. If you look at a resistor one end should have a gold silver or white band.

They can also be used to provide a specific voltage for an active device such as a transistor. Before you can test a resistor you need to know its strength and tolerance.
