What is a non-inverting op-amp circuit?
- AAn operational amplifier circuit connected such that the input and output signals are 180 degrees out of phase
- BAn operational amplifier circuit connected such that the input and output signals are in phase
- CAn operational amplifier circuit connected such that the input and output signals are 90 degrees out of phase
- DAn operational amplifier circuit connected such that the input impedance is held low, and the output impedance is high
Correct answer: B — An operational amplifier circuit connected such that the input and output signals are in phase. From the official ISED question bank, verified word for word.
Why
A non-inverting op-amp circuit keeps the input and output signals in phase, meaning when the input voltage rises, the output voltage rises at the same time without flipping direction. The full explanation — and one for every question — is in Pro.
