Actually curent or voltage that passes through the object . then there will be a loss .if (current or voltage) the electrical energy is converted into light source , mechanical energy( rotation of fan),chemical reaction(electroplating) as heat (iron box ). so when no object(load) is connected to the plug point there wont be any loss if you r switch on the switch too.
Most plugs have a wire attached which has an outlet or an appliance attached. If your plug has no wire attached the answer is --no power is used. If you are talking about the plug of an extension cord with nothing attached to the outlet, the answer is no. But if you mean that the other end of the wire attached to the plug is attached to an appliance which is not turned on the answer is, sometimes. Some appliances have internal clocks or Transformers or circuits that use power while the item is in the off mode.
No, if nothing is plugged in pulling current then you are using no electricity by leaving the switch in the on position.
some do, it depends. Tvs waste electricity because it would be easier to turn them on, not take really long. Lights dont.
No the receptacle itself does not consume any power it is just a source of power. No amperage is used until the load is plugged in and turned on. Appliances plugged in with the switch in the off position draw no current. Devices that do not have an off- on switch will start drawing power as soon as they are plugged in. Once an appliance is switched on you are billed for the use of the electricity.
Yes. You can tell if the adapter is warm then there is a waste of energy. It is the excitation of the transformer that is causing the heat loss.
It is plugged into a wall outlet.
If there is no load plugged into the cord there will be no power consumed. The only time the resistance of the cord will come into effect is when the circuit becomes energized through the load plugged into the end of the cord.
they only use electricity when an appliance is plugged in and switched on
By leaving things such as lights on when they are not in use. Even leaving things such as lamps, your laptop, etc plugged in to the wall socket when they are not in use drains and wastes electricity.

Generally, yes. You are powering the clock and probably the timer circuits.
Misuses of electricity will entail leaving the lights on when someone exits a room, as well as such things like leaving the television on or even plugged in when not in use. This wastes electricity as well as money.
Standby power <><><> Sometimes referred to a "Vampire Usage"- the power consumed by leaving a charger plugged in, even when not charging a device.
No, nothing will happen . Electricity is not flowing
Everything that is plugged into the mains socket and switched on will use electricity even if it's a battery charger with no batteries in. So yes they do draw electrical power from the mains.

None
