How much does it cost to charge an ipad?

3 euros per year. The Electric Power Research Institute has compared the electricity costs per year for the operation of different devices in a list. One conclusion is that iPads can drastically contribute to decreasing power consumption.

Can you leave the charging cable in the socket?

It is better not to leave your charging cable permanently in the socket. This is not particularly dangerous, but the small devices eat up electricity unnecessarily.

Is electricity consumed when the plug is in the socket?

The following applies: Everything that is plugged into a socket draws electricity. As long as the plug is in the socket, the devices draw energy – for two to six euros a year.

What happens when you put something in the socket?

What exactly happens in an electric shock? When in contact with electricity, the human body itself becomes a conductor. Electricity flows through the body. This can lead to muscle spasms (tetany) and cell destruction.

Is electricity from the socket deadly?

For a touch voltage of 230 volts (which most electrical devices operate at) and a body resistance of 1,000 ohms, this results in a flow rate of 230 milliamps. Even an electric shock of this magnitude can be fatal.

What to do if you reach into the socket?

Electric shock: what to do?Call 911 or ask another first aider to do so.Before providing first aid in the event of an electric shock, for your own safety you should disable the power source as much as possible: unplug the electrical appliance or remove the fuse.
