Resistors are essential components of a robot or any electronic device for that matter.

How to read resistors with a multimeter. Dial your multimeter to the resistance range you think the resistor fits in. The manufacturing process isnt perfect so most resistors are a little off. Resistors regulate the amount of current flowing in an electronic circuit.

Observe the reading on the display. How to test resistors. Three of the bands tell you the nominal value which means the value the resistor was designed to havethe fourth band tells you the tolerance of the resistor which indicates how far off the nominal value the actual resistance could be.

Your multimeter should be set to a higher value than you are going to measure. It acts to limit the flow of electricity from the battery to different parts of the device in order to reduce waste and increase efficiency. A good resistor should test within its rated range.

Resistors are probably the easiest component to test with a multimeter. For example if you want to measure the voltage in a wall socket and your multimeter has both 50v and 250v ac settings set it to 250v ac. Move the dial to the next range up until you get a valid reading.

For example if a circuit required the use of a transistor but the. If your multimeter reads at close to 0 zero you guessed too high of a value. If you read your multimeters manual or spec sheet you will find that the maximum continuity resistance is higher than.

Resistors are designed to decrease electrical current. Therefore it is equally important to be able to measure the resistance of a resistor when it comes to assembling your own robot. If you suspect a bad resistor is at the root of your electrical problems you can conduct a simple test with a multimeter without ever removing the resistor from the circuit.

Otherwise you will not be able to measure the full voltage and you may damage your multimeter. If your multimeter reads 1 you guessed too low of a value. There are two main types of resistors.

What happened is that the resistance of your resistor was low enough to trigger a continuity reading on your multimeter. A multimeter is needed as well as.
