voltage force that pushes electrons (v)
current net movement/flow of electrons mesured in amps (i)
Resistance measured in ohms (r)
Fuse Metal that melts

Electric power related to voltage diff and current
Electric power formula power(watts)=(current/amps/i)x(volts)
elctrical energy rate at which electrical power is changed to other form measured in kWh
electrical energy formula kWh=watts x hours energy=power x time
