Cool, just wondering why it is a negative terminal ?VB = VA otherwise the OP-AMP is not operating as an amplifier. Fix this and you should be right.
This is a non-inverting amplifier, the input being applied to the (+) input.
Why what is a negative terminal?Cool, just wondering why it is a negative terminal ?
(-) is the inverting input of the OP-AMP, used here for negative feedback of some output to reduce the gain from its high open-loop value. The circuit's voltage input is applied to the (+) non-inverting input of the OP-AMP.On diagram it has (-) for non inverting input.
