Easy household electrical tests

Do electrical things not work?

You can try hundreds of electrical things in your home, from appliances to batteries. It is really quite simple.

Appliances convert electrical tests into another form of energy. It includes large and small appliances, computers, phones, lighting and more. Electrical objects convert electrical energy into motion, heat, cold, light, sound, images and many other useful services.

All you need to test appliances is a low-cost continuity tester or a multimeter available at hardware stores. A multimeter (less than $ 20) measures the amount of energy (voltage) applied, the electricity (current) used and the resistance to overcome to get the job done. The power is measured in volts (V), the current is counted in amps or amps (A) and the resistance is calculated in ohms (O).

There is still an electric term that you have probably heard. Defining it will be useful when repairing electrical devices. A watt is the amount of energy consumed by an electrical device when it is running. A 750-watt toaster, for example, uses 750 watts (watts) of power to roast your wheat, rye, yeast or other bread in the morning.

Continuity tester

Electricity needs a route or a continuous circuit to circulate. It is like a two-lane road from point A to point B and vice versa. A continuity tester is useful for checking cables and wires to make sure they can conduct electricity.

To use a continuity tester, follow these steps:

1. Unplug the power supply cable (power outlet).

2. Make sure all device switches are turned on.

3. Place the continuity tester tie on a cable pin.

4. Put the tip of the continuity tester in contact with the other pin. If there is continuity, the tester will turn on. Otherwise, it will not be the case.

This is what happens: the continuity tester sends electricity from an internal battery through a cable pin and along with the cables. If the light receives electrical energy tests from the other branch, it illuminates, which means that the path is good. Otherwise, something stops him. Remove the cable from the device and test each of the two cables separately to see which one does not work. If both work, the short circuit is in the device itself.

Multimeter

A multimeter (also called voltmeter-ohmmeter or VOM) is another way to test continuity. Use it to measure the amount of alternating current (AC or household) or direct current (DC or battery) in a connected or powered circuit. You can also check the voltage. In addition, a multimeter can verify resistance. A continuity tester verifies resistance, but answers yes or no. A multimeter checks the resistance and reports how many ohms (resistance measurement) a circuit has.

You can use a multimeter to test motors, switches, controllers and many other electrical devices. See the multimeter instruction sheet for more details.

Here’s how to use a multimeter to test an electrical device:

1. Unplug the power supply cable, except when testing a live circuit.

2. Connect the test leads to the multimeter.

3. Select the function (ACV, DVC, resistance) and range (maximum expected reading).

4. Connect the probes to the cable or component of the device.

5. Interpret the reading. See the product manual for advice on what is wrong and what you can do about it. In addition, there are many resources online.

Do not let a simple electrical problem prevent you from using the power of electricity. Some simple electrical tests can help you repair broken household items, instead of throwing them away.
