AC theoryQuestion 969 of 1506

A resistor and a capacitor are in parallel on an AC supply. What is true of the voltage?

  1. It is larger across the capacitor
  2. It is larger across the resistor
  3. It is split between them by their impedances
  4. It is the same across both
Show answer

Correct answer: It is the same across both

In any parallel circuit every branch has the full supply voltage.
