V

Voltage (Pressure)

The electromotive force pushing charge through a circuit. Higher pressure means a higher potential to do work.

I

Current (Flow Rate)

The actual volume of electrons (charge carriers) passing a point per second, measured in Amperes.

R

Resistance (Restriction)

The physical opposition to flow. Like a narrowing pipe or friction that restricts the flow rate.
