How Do You Test A Resistor With An Ohmmeter?
The ohmmeter serves a useful purpose when measuring the resistance of a resistor. Placed in a circuit, a resistor reduces the voltage necessary for a specific part of the circuit to operate. If the voltage isn’t reduced, sensitive components in a circuit can be damaged. If a resistor goes bad in a circuit, those components may cease to operate. Troubleshooting the problem resistor requires the simple use of the very simple ohmmeter. Use the schematic diagram for the circuit you are testing to determine what the value of the suspected resistor should be. The resistance of a component in a schematic diagram is written next to the resistor’s zig-zag symbol. Set the ohmmeter selector dial to the next-higher value than the value of the resistor you will be testing, and connect the test probe wires to the correct jacks on the meter: the black wire plugs into the negative (-) jack (or into the “Ohms” jack if using a digital multimeter) and the red wire plugs into the positive (+) jack.
