Current and Voltage gain using an Op-Amp
Added by M Hoben on Dec 15, 2008
This activity examines how an op-amp and transistor can be combined to provide current gain and voltage gain. Examples are given of the op-amp being used, in series with a transistor, in the comparator and inverter modes, and practical uses of such circuits are outlined.
