Three matching resistors are connected in series to a cell. Voltmeter Q gives a reading of $8.0\,\text{V}$. What value does voltmeter P show, and what is the e.m.f. of the cell?
- Areading on P $= 4.0\,\text{V}$, e.m.f. of cell $= 8.0\,\text{V}$
- Breading on P $= 4.0\,\text{V}$, e.m.f. of cell $= 12\,\text{V}$
- Creading on P $= 8.0\,\text{V}$, e.m.f. of cell $= 8.0\,\text{V}$
- Dreading on P $= 8.0\,\text{V}$, e.m.f. of cell $= 12\,\text{V}$
