31.
For dc the current through coupling capacitor in CE amplifier circuit is
Answer: Option
Explanation:
dc remains confined within BJT. Only ac signal comes out.
32.
In a CE amplifier the collector resistance is short circuited. The ac output voltage will
Answer: Option
Explanation:
Since the output is taken across collector resistance, short-circuiting collector resistance will decrease output voltage.
33.
In a transistor CE mode, VCC = +30 V. If the transistor is in cut off region, VCE =
Answer: Option
Explanation:
When transistor is in cut off region VCE = VCC .
34.
The dc load current in a bridge rectifier circuit is 10 mA. The dc load current through each diode is
Answer: Option
Explanation:
Since both diodes contribute equal load current, each diode current is 5 mA.
35.
