A student sets up a circuit containing three identical cells. Each cell has an e. mf. (electromotive
force) of 2.0V.
Fig. 8.1 shows the cells in series with a length of uniform metal wire connected between two
terminals Kand L, an ammeter and a resistor X.
Fig. 8.1
(a) State the total e. mf. of the three cells in series.
total e. m.f. =
[1]
(b) The ammeter reading is 0.25A.
