Three identical resistors, each of resistance R, are arranged so that two are connected in parallel with each other, and this parallel pair is connected in series with the third resistor across an ideal battery. Which statement best describes the potential difference across one of the parallel resistors compared with the potential difference across the series resistor?
(a) The potential difference across a parallel resistor is equal to that across the series resistor.
(b) The potential difference across a parallel resistor is less than that across the series resistor.
(c) The potential difference across a parallel resistor is greater than that across the series resistor.
(d) The potential difference across a parallel resistor cannot be determined without additional information.
