CIRCUIT PROBLEMS
MICROELECTRONICS QUESTIONS &
CORRECT ANSWERS
A coupling Capacitor is

A) A dc short
B) An ac opem
C) A dc open and an ac short
D) A dc short and an ac open - Correct Answer ✔✔ C) A dc open and an ac short
When a coupling capacitor is a dc open the same capacitor will act as an ac
short(short).

For dc circuits, the current in a coupling circuit is
a) Zero
b) Maximum
c) Minimum
d) Average - Correct Answer ✔✔ A) Zero
- coupling circuit is a series capacitor zero because it is dc act as open , I (current) is
open means its zero .

The capacitor that produces an ac ground is called a

A) Bypass Capacitor
B) Coupling Capacitor
C) DC open
D) AC open - Correct Answer ✔✔ A)Bypass Capacitor
The capacitor produces a AC ground because AC act as a short. Shorting it out makes
it a bypass capacitor

The ac equivalent circuit is derived from the original circuit by shorting all

A) Resistors
B) Inductors
C) Capacitors
D) Transistors - Correct Answer ✔✔ C) Capacitors
AC = what's being shorted is the capacitors

The output voltage of a Common- Emitter (CE) amplifier is
A) Amplified
B) Inverted
