Ampere (A) — Electric current measures the rate of flow of charge, measured in Amperes.

Resistor — Resistors consume power, and don't provide gain or directionality.

V = I * R — This is Ohm's Law. Voltage is directly proportional to current and resistance.

To protect the circuit from overcurrent. — Fuses break the circuit if the current exceeds a certain value, preventing damage.

Negative — Electrons carry a negative electrical charge.
