# Electricity --- **Electricity** is a concept in [[physics]] that has to do with how [[atom#Electrons Electron Shells|electrons]] flow from one place to another. zap! see such related topics as: [[resting membrane potential]] ## Ohm's Law **Ohms law** is a law for determining the relationship between **voltage**, **current** (or **amperage**) and **resistance**. Voltage = Current x Resistance If we consider electricity moving through a wire to be like water moving though a pipe, the resistance is the size of the pipe, the voltage is how much volume of water there is to move, and the current is the speed that the water moves. ___
