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.

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.

What will cause a block heater cord to catch fire?

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
