6.
A 120 V, 30 Hz source feeds a half wave rectifier circuit through a 4 : 1 step down transformer, the average output voltage is
Answer: Option
Explanation:
.
7.
The slew rate of an ideal op-amp is
Answer: Option
Explanation:
Slew rate signifies the fastest change which can occurs in output voltage. In an ideal op-amp the output can change instantaneously.
