Question

For an n-p-n transistor in the common-emitter (CE) configuration, draw a
labelled circuit diagram of an arrangement for measuring collector current as
a function of collector-emitter voltage for at least two values of the base
current. Draw the shapes of the curves obtained. Define the terms (a) output
resistance and (b) current amplification factor.​

Answer 1

Answer:

ammeter

An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
