2 Primary Types of Voltage: - [[Direct Current]] - [[Alternating Current]] - is the difference in charge/potential between two areas - creates potential for flow through resistance - one volt is the potential to drive on coulomb of charge through a resistance of one ohm per sec - akin to water pressure in a water system, higher volt leads to higher current - if a piece of metal is at one volt - it means that every electron in that metal as the energy of 1 eV - eV (electron volt) is a unit of energy - is the typical amount of energy for a single atom or molecule - $1.6$ x $10^{-19}$ Joules https://www.youtube.com/watch?v=w82aSjLuD_8
