Problem

While traversing a closed loop, a student records an abrupt increase of

5\,\text{V}

in the potential–position graph followed immediately by an abrupt decrease of

0.7\,\text{V}

. Which pair of ideal circuit elements, in the order encountered, is most likely responsible for these two successive steps? (a) A

5\,\text{V}

resistor followed by a forward-biased silicon diode (b) A

0.7\,\text{V}

battery followed by a

5\,\text{V}

resistor (c) A

5\,\text{V}

battery followed by a forward-biased silicon diode (d) A

5\,\text{V}

battery followed by a reverse-biased silicon diode
