Fluctuations in electricity can occur due to various reasons. Here are a few possible explanations for the issues you described:
Voltage Drop: When high-power appliances like air conditioners, microwaves, or refrigerators turn on, they require a significant amount of electricity. This sudden power demand can cause a temporary drop in voltage, resulting in dimming lights or fluctuations in power supply.
Electrical Wiring: Faulty or inadequate electrical wiring can contribute to voltage fluctuations. If the wiring in your house is old, damaged, or not properly installed, it may struggle to handle the power demands of multiple appliances simultaneously.
Overloaded Circuits: If your electrical circuits are overloaded, it can lead to voltage drops. When too many appliances are connected to a single circuit and operated simultaneously, it exceeds the circuit's capacity, causing voltage fluctuations.
Loose Connections: Loose electrical connections, particularly at outlets, switches, or circuit breakers, can cause intermittent power disruptions and fluctuations. These loose connections may result in increased resistance and voltage drops when appliances draw power.
Electrical Panel Issues: If your electrical panel is outdated or not properly functioning, it may struggle to distribute electricity evenly throughout the house. This can lead to power fluctuations and dimming lights when high-power appliances are in use.
It's important to address these issues to ensure the safety of your electrical system. If you're experiencing persistent or concerning electrical fluctuations, it's advisable to consult a licensed electrician. They can assess your electrical setup, identify any underlying problems, and provide appropriate solutions or repairs to stabilize the power supply in your home.
