Electricity – Video 1 – Second Timers Quiz

ELECTRICITY AND ELECTRONS: The electrons circling an atom are very small. If the nucleus in an atom was the size of a basketball, the electrons circling it would be the size of a grain of sand.

ELECTRICITY AND ELECTRONS: The electron is 1/80 of the weight of a proton.

ELECTRICITY AND ELECTRONS: Electricity is the movement of the protons in and around atoms in, for instance, copper wire.

ELECTRICITY AND ELECTRONS: When electricity travels through a wire in a house, usually the wire the electrons are moving through in a house is made of either copper or aluminum. Air conditioners might have aluminum wire.

HOUSE ELECTRICITY AND NERVE ELECTRICITY: Electricity in wires and batteries is the “movement” of electrons.

HOUSE ELECTRICITY AND NERVE ELECTRICITY: Electricity in wires is the “movement” of negatively charged electrons like when electrons move from a battery to a quadcopter.  Electricity in nerves is the movement of positively charged hydrogen atoms (ions) into the nerves.

HOUSE ELECTRICITY AND NERVE ELECTRICITY: Electricity in nerves is the movement of positively atoms (ions) into the filaments of the nerves. 

HOUSE ELECTRICITY AND NERVE ELECTRICITY: Sodium atoms are sodium ions that have lost one electron.

HOUSE ELECTRICITY AND NERVE ELECTRICITY: When a message runs down the nerve at the speed of a dragster (270 mph), sodium ions are rushing into the nerves giving the nerves a positive charge.

HOUSE ELECTRICITY AND NERVE ELECTRICITY: Sodium ions are positively charged because a proton is knocked off the nucleus.
