More questions
Correct Answer: apparent power
Correct Answer: zero
Correct Answer: 451.0 mV
Explanation:
Some AC Voltage Conversion:
Peak to rms: multiply peak by 0.707.
Peak to average: multiply peak by 0.637.
Rms to peak: multiply rms by 1.414.
Rms to average: multiply rms by 0.9.
Average to rms: multiply avg by 1.111.
Average to peak: multiply avg by 1.567.
Mostly voltmeter shows rms value. So, Vav = 0.9*Vrms
= 0.9*500.
= 450mV ~ [D] 451 mV.
Correct Answer: False
Correct Answer: 147.5 kHz to 152.5 kHz
Correct Answer: The larger of the two reactances is dominant.
Correct Answer: True
Correct Answer: ripple
Correct Answer: edge-triggered
Correct Answer: voltage
