when an appliance is turned on, an electric current flows. | current |
the higher the number of volts the more energy supply that is needed to drive the higher the number of volts the more energy that is needed to drive the electrons around the curcuit. E.G. different light globes. | voltage |
the measure of how different it is for a current to move through a wire. | resistance |
measured in watts (w) or kilowatts(Kw) 1000W=1Kw. | power |
the switch must be ... when the power is on. | closed |
the switch must be ... when the power is off. | open |
the power source in a curcuit | battery |
the object that glows when the curcuit is properly set up. | globe or bulb |
