Limiting action happens in series when a diode is________ and in parallel when a
diode is________. - ANSWERReverse biased, forward biased.
What is the purpose of a diode limiting circuit? - ANSWERTo limit amplitude of the
input.

resistance in emitter base to? - ANSWERHigh resistance in collector base.
Ie (Emitter current) = ? - ANSWERIb (base current) + Ic (collector current)
