small base current controls the larger collector-emitter current through a small base current controls the larger collector-emitter current through a
process called current amplification. process called current amplification.
This happens because of how voltage works. Voltage is the potential difference When a small voltage is applied to the base, it allows a small current to flow
between two terminals in a circuit. A high voltage increases the flow of current from the base to the emitter. This base current triggers a much larger current
whereas low voltage restricts or reduces it. to flow from the collector to the emitter. Think of it like a water valve: a
small turn of the handle (base current) can control a large flow of water
It follows from this that when the voltage at the base is high, a current flows (collector-emitter current). The transistor amplifies this effect, allowing a

voltage at the base is low no current flows from the collector to the emitter
and the transistor is "off".
