Does an extension cord use power if nothing is plugged into the other end?

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.

∙ 12y agoif the PowerPoint that your extension cord is plugged into is turrned on then yes it will draw power, but very little unless there is an applience plugged into the other end, in which case it will use more electricity
Wiki User

Does leaving the switch on to a switched outlet use electricity if nothing is plugged into the outlet?
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.

Does an electrical receptacle draw power?
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.

A break in the electrical wiring inside the cord - usually it is right by the male end that you are plugging in to power - so a replacement end can be put on the block heater cord ( those flames sure can startle a person ! ) After it happened to me , I always made sure that I plugged my block heater cord into my extension cord before I plugged my extension cord into the electric outlet
