The lights in my house are flickering. What is the reason?

1, the cause of the current.

Turn on the light at the peak of power consumption, and the total resistance decreases due to the increase of load. According to ohm's law, the current on the transmission line increases, and the power lost on the transmission line also increases, so the voltage at both ends of the household circuit is relatively low, and the actual power of the bulb is small, so it is relatively dark.

There are few users who use electricity in the middle of the night, the current on the main road is small, and the power loss on the line is small, so the voltage at both ends of the home circuit is larger than that at the peak of electricity consumption, and the actual power of the light bulb is large, so it is brighter.

2. Ballast aging or poor quality is greatly affected by weather and humidity.

3. The fault is just that the lighting in one bedroom is not working normally, and the new light bulb is still like that, which can rule out the possibility of lighting problems. It is estimated that the problems are related to the line and voltage. However, considering that only one room has the above phenomenon, the possibility of voltage instability can also be ruled out, and it is important to check whether the line is in poor contact.

Electrical maintenance methods:

1. All electrical appliances are the same and need to be dustproof. Therefore, when the appliance is not used for a period of time, it is best to cover it with a clean and dry cloth or nylon sleeve, which can prevent dust.

2. When the electrical appliances are not used, it is best to unplug or turn off the power supply. Although the standby state cannot work normally, it will also consume some electrical appliances. Unplugging the plug can not only prolong the life of electrical appliances, but also save electricity.

3, the correct use of electrical appliances, you must first turn off the operation of the appliance itself, and then unplug the main plug or turn off the main power supply, do not directly unplug the power plug when the appliance is running, which will cause losses to the appliance.

4. Electrical appliances have been used for a long time, so we must pay attention to cleaning, especially the internal cleaning of electrical appliances. Pay attention to spare parts when disassembling, don't lose spare parts, and don't install the wrong spare parts when reassembling.

If there are many electrical appliances at home, it's best to check the safety of some of your electrical appliances regularly. The common electrical appliances that need to be checked are electric water heaters and electric heaters.
