  • When measuring the voltage, the emitter terminal must be connected to the ground for accurate readings.
  • emitter surface

Examples

  • In a transistor circuit, the emitter is responsible for injecting charge carriers into the base.

  • And so just so we know what they are, there's an emitter, a base and a collector.

  • So if you have this is your emitter, you have a contact here and a contact here.

  • You can see there between the emitter and the base, between the base and the emitter, there's no reading.

  • And then the current is flowing out of the emitter back-to-back to ground over here.

  • And then you'll have an emitter, a base and a collector.

  • And then we have common emitter single transistor amplifiers and they're coupled together with this pot here.

  • The bipolar transistor (a) functions by emitting electrons across a low-impedance, forward-biased emitter junction into the base region.

    Academic text (1997)
  • The engineer replaced the faulty emitter to ensure that the circuit functioned properly.

emitter singular
emitters plural

Morphology

emitter = emit (transparent) = emit + er

Formed by a regular agentive suffix '-er' added to the verb 'emit'; meaning 'one/that which emits' is directly derived.

Etymology

Emitter comes from the Latin emittere, made of e- 'out' and mittere 'to send', like in transmit or the simple word 'send'. So, in a transistor, the emitter is the part that 'sends out' charge into the circuit.
