OP AMPS

Today we learned about OP Amp , an electronic unit that behaves like a voltage controlled soure.
we listed 5 sources Transistor, resister, diode, current supply and voltage supply that we used or learned about so far.

We predicted following graph of an equivalent circuit. Amplitude was much higher in equivalent circuit and it was off in entire region because of no current flowing.

Operational amplifier can switch between positive and negative where transistor amplifier are not able to do that.

We redrew following amp circuit with some internal resistor.

Following is the example of non ideal amplifier that we did in class.

We built following non ideal op amp circuit.  Measured vout values and compared it with v expected.

Graph of v out vs v in.
