The nucleus of the atom contains protons(positively charged)and usually neutrons(no charge)around which whirl electrons(negatively charged) This is called a whirlygig. An electron is 2000 times smaller in mass than proton but its electrical charge is equal to that of a proton.Electrons of many elements,particularly metals,are easily knocked off from there parent atoms and can wander freely in the atomic structure.If a state of unbalanced exists,these constitute a n electric current.When a battery or other source is attached to a wire,it releases electrons into the wire.They bounce against the free electrons in the wire which are repelled because they have the same electrical charge.they go on bouncing against other free electrons down the wire causing an instantaneous pressure wave. provided there is somewhere for them to go,such as a lamp or a motor,the electrons flow out to the far right hand side of the whirlygig. So the answer to your question is yes , as long as you don't let the neutrons get knocked off your whirlygig.
