Voltage gain for an amplifier is 100 while it is operating at 10 volts. What is the O/P voltage when I/P is 1 volt?

Explanation

  • Voltage gain of the amplifier is 100.
  • If the operating voltage is 10 volts then its output voltage will be volts.
  • Voltage gain of the amplifier does not depend on input voltage. It remains same whatever the input voltage is present.
  • So, here voltage gain will remain 100 even if input voltage is changed from 10 volts to 1 volt.
  • Output voltage,
