EC33: For Operational amplifier configurations, a student is analysing a Zener stabilised supply. Which option gives the best Summing amplifier configuration reasoning for the objective "Apply summing amplifiers to signal processing contexts"?.
- A.EC33 correct: In the Zener stabilised supply, the answer follows the signal path from input condition to component response to output change, so it supports Apply summing amplifiers to signal processing contexts.
- B.EC33 distractor: It names a component but does not connect the input condition to the measured output in Summing amplifier configuration.
- C.EC33 distractor: It reverses the cause-and-effect chain, so the output is explained before the circuit condition is set.
- D.EC33 distractor: It gives a generic electronics definition without applying the Zener stabilised supply context.
Model answer
What a good answer should say
- The correct option is EC33 correct: In the Zener stabilised supply, the answer follows the signal path from input condition to component response to output change, so it supports Apply summing amplifiers to signal processing contexts.
Explanation
Why this works
It is best because it keeps Summing amplifier configuration anchored to the circuit signal path: input condition, component response, then output change. The distractors are wrong because they omit the output link, reverse the electronics causality, or drift into a generic component definition rather than applying the Zener stabilised supply.
