How do extension cords work?
An extension cord is a flexible cord that has a plug on one end and a socket on the other end. It is used to connect an electrical device to a power source that is farther away than the length of the device’s cord will allow.
Extension cords work by allowing electrical current to flow from a power source, through the cord, and to the device that is plugged into it. They have a conducting wire inside the cord that is covered by an insulating material to keep the electricity contained within the cord. The wire is made of a metal, typically copper, because copper is an excellent conductor of electricity.
Types of extension cords
- Indoor extension cords
- Outdoor extension cords
- Heavy-duty extension cords
How to safely use an extension cord
It is important to use extension cords safely to avoid electrical shock or fire hazards. Here are some tips:
- Use the right cord for the job
- Do not overload the cord
- Do not plug one extension cord into another
- Unplug the cord when not in use
- Inspect the cord regularly for damage
Does leaving an extension cord plugged in use electricity?
Yes, leaving an extension cord plugged in uses electricity even if the device it is powering is not turned on. This is because the cord itself is using electricity, especially if it is plugged into a live socket.
| Device | Watts used when turned off |
|---|---|
| Laptop | 1.3 watts |
| TV | 1-5 watts |
| DVD player | 0.5-1 watt |
While the amount of electricity used is small, it can add up over time. To minimize energy waste, unplug your extension cords when they are not in use, or use a power strip with an on/off switch to control the flow of electricity to your devices.

Understanding standby power usage
In today’s modern society, almost all household appliances and electronics come with standby mode – a mode that allows the appliance or electronic device to remain connected to the power source even when not in use. Although this feature is convenient, it contributes to a phenomenon known as standby power usage.
Standby power usage, also known as vampire power or idle load, is the energy consumed by appliances and electronic devices that are connected to the power source but are not actively being used. This phenomenon occurs because most electronic devices do not completely shut off when turned off – they remain in standby mode, ready to be turned back on as soon as a user needs them. Standby power usage, though in small amounts, can accumulate over time and account for up to 10% of the total electricity consumption in a home.
- Standby power usage occurs when electronic devices, appliances, and chargers remain connected to a power source even when not in use.
- Appliances and electronic devices in standby mode continue to consume power even though they are not providing any output or action.
- Standby power usage contributes to energy wastage and can account for up to 10% of the total electricity consumption in a home.
According to the US Department of Energy, standby power usage in a typical household can cost between $100 and $200 per year. This cost could be avoided by unplugging devices from the power source when not in use.
| Electronic Device | Standby Power Usage (watts) |
|---|---|
| 12-Watt Charger | 0.5 |
| Television | 1-5 |
| DVD Player | 2-3 |
| Computer Monitor | 1-6 |
