Power resistors are devices which dissipates electric current as heat. They can be used alone or in a series to effectively spread out the flow of electricity. Below are step by step instructions for how to connect these devices and use them properly.
The first step is to activate the multimeter by turning on the switch. The red probe needs to be plugged into the positive port, while the black one should be plugged into the negative. Next, the dial should be turned on the multimeter so that the DC voltage can be measured. Voltage is generally marked by a large V surrounded by wavy lines.
Then the person should take the red lead and connect it to the positive terminal on the battery or other power source. The black lead will be touched on the negative terminal. Write down the number which appears on the voltage meter, as it will be necessary to use in the next step.
The next step involves a little simple math. Divide the number from the voltage meter by the electric current that will be necessary to get the desired resistance. For example, if the person needs two amps it will take twelve volts to obtain six ohms. This step is necessary for the person to know precisely the amount of voltage necessary to get the desired resistance.
The last step is to combine resistors in a row until the desired resistance is reached. The only way this will be effective is by using a single wire that runs between all of the resistors. There are any number of combinations that would work, for example a person might use a three ohm, two ohm, and one ohm resistor to get to the necessary six ohms.
By following these instructions a person will be able to effectively use power resistors to dissipate electric flow. These steps should be taken with caution and only by people who have a basic understanding of electric work. If this project seems like too much the safest thing to do is to call in a professional.
