A circuit includes a cell with electromotive force (e.m.f.) $2.0\ \text{V}$, three resistors, three ammeters and two voltmeters. One ammeter is marked P and one voltmeter is marked Q. The readings on the other two ammeters and on the other voltmeter are given. What are the readings on ammeter P and on voltmeter Q?
- AP: $1.5\ \text{A}$, Q: $1.5\ \text{V}$
- BP: $1.5\ \text{A}$, Q: $2.5\ \text{V}$
- CP: $2.5\ \text{A}$, Q: $1.5\ \text{V}$
- DP: $2.5\ \text{A}$, Q: $2.5\ \text{V}$
