Is there any waste of electricity here?
Yes, there is a potential for phantom load or standby power waste of electricity in this setup.
💡Here's why:
* The image shows a USB charger block (likely for a phone or tablet) plugged into the wall socket.
* The charging cable is connected to the block, but the other end (the connector, circled on the left) is not plugged into a device.
Explanation of Waste
Even when no device is actively charging, the charger block itself can draw a small amount of power from the wall socket. This is often called:
* Phantom Load: Electricity consumed by appliances and chargers when they are plugged in but are either turned off or not performing their primary function (like the charger sitting idle).
* Vampire Power: This low-level, continuous power draw is wasted energy over time.
While the amount of power consumed by a single idle charger is very small (often less than a watt), it adds up globally and over many hours.
How to Stop the Waste
The waste can be easily eliminated by:
* Unplugging the charger block from the wall socket when not in use.
* Turning off the switch that controls the socket where the charger is plugged in (the switch circled on the right).
