A student investigates a hand-cranked DC generator connected to a center-zero analogue voltmeter.

In state X, the student turns the generator's handle at a constant speed, producing the reading shown on Voltmeter X. In state Y, the student rotates the handle differently, producing the reading shown on Voltmeter Y.

Voltmeters X and Y

Which of the following correctly describes the rotation of the handle in state Y compared to state X?

Speed of rotation: Y is slower than X; Direction of rotation: Y is the same as X

Speed of rotation: Y is slower than X; Direction of rotation: Y is opposite to X

Speed of rotation: Y is faster than X; Direction of rotation: Y is the same as X

Speed of rotation: Y is faster than X; Direction of rotation: Y is opposite to X
