The diagram illustrates two voltmeters P and Q connected to a potential divider. The sliding connection at point X is moved upwards towards the top of the diagram. What effect does this have on the reading on P and on the reading on Q?
- Areading on P decreases; reading on Q decreases
- Breading on P decreases; reading on Q increases
- Creading on P increases; reading on Q decreases
- Dreading on P increases; reading on Q increases
