An ammeter is connected in series so that the current to be measured passes through it.
Thick connecting wires have very small (negligible) resistance.
The p.d. across the terminal of the cell when current is being drawn from it is called terminal p.d. It is smaller than e.m.f. of the cell.
Constantan (Cu 60%, Ni 40%).
