AC theoryQuestion 1001 of 1506

What does a Bode plot show?

  1. Voltage against current at one instant
  2. Amplitude or phase against frequency
  3. Power against time over a full cycle
  4. Resistance against temperature
Show answer

Correct answer: Amplitude or phase against frequency

It shows how a circuit responds as the frequency changes.
