Electrons emitted by a hot filament are able to cross the gap between the filament and the plate. What force enables them to do this?
Magnetic repulsion
Inductive reactance
Thermionic emission
Electrostatic attraction
The getter in an electron tube serves what purpose?
It protects the plate from overheating
It allows the cathode to emit more electrons
It helps to produce a better vacuum
It anchors the tube elements in the base
Why does control grid voltage of a triode exercise greater control than plate voltage over conduction of the tube?
The grid is operated at a higher voltage than the plate
The grid adds electrons to the electron stream
