Wattage (Power)
Ohm’s Law defines the proportional relationship between Potential Difference (V) and the resulting Electron Flow (I). In a perfect conductor, current is directly proportional to voltage and inversely proportional to its impedance.
Voltage (Pressure)
The electromotive force pushing charge through a circuit. Higher pressure means a higher potential to do work.
Current (Flow Rate)
The actual volume of electrons (charge carriers) passing a point per second, measured in Amperes.
Resistance (Restriction)
The physical opposition to flow. Like a narrowing pipe or friction that restricts the flow rate.
"To visualize the invisible, we compare the movement of charge to the movement of water."
