Assume an operational amplifier is working on inverting amplifer in which it takes input resistance and feedback resistance of 30 ohm and 60 ohm respectively. If input voltage is applied at 150 volt then examine following parameters1.Evaluate over gain of amplifier2.Evaluate the gain of opamp if input voltage is applied on non inverting amplifier3.Calculate output voltage of amplifier4.If input voltage is changed from inverting terminal to non inverting terminal then calculate its output voltage5. If we add one more input resistance of 40 ohm at inverting terminal at 20 voit input supply voltage and working as adder then calculate the output voltage.
