A sinusoidal voltage e = e₀ Sin (wt) is fed to a common emitter amplifier. Draw neatly labelled diagrams to show:

(i) Signal voltage

(ii) Output voltage of the amplifier.

Electrons, initially at rest, are passed through a potential difference of 2 kV. Calculate their:  

(i) Final velocity and

(ii) de Broglie wavelength.
