Ampere — Electric current is measured in Amperes (A).

Resistor — Resistors, capacitors, and inductors are passive; they don't amplify or switch signals.

V = I * R — Ohm's Law states V = I * R

Ohm — Resistance is measured in Ohms (?).

Current — Current is defined as the flow of electric charge, which in most cases is the flow of electrons.
