Ampere (A) — Electric current is measured in Amperes, named after André-Marie Ampère.

Resistor — Resistors only consume power and do not amplify or control current/voltage flow actively.

V = I * R — This is Ohm's Law, describing the fundamental relationship between voltage, current, and resistance.

To protect the circuit from overcurrent — Fuses are designed to break the circuit if the current exceeds a safe level, preventing damage.

Alternating Current — AC stands for Alternating Current, referring to a current that periodically reverses direction.
