Hi,
Hoping for a prompt in the right direction regarding a unkown voltage on a Non Inverting Op Amp.
Reading through my notes i understand how the resistors R3 and R2 set up a potential divider which supply the Inverting input on the Amp.
And the fact that neither input is connected to Earth means the Virtual earth principle cannot be used.
My course notes show that:
V−=V+ because the op-amp is ideal and V+=Vin
So is this as simple as as saying V- =100mV ???
Any help would be greatly appreciated
