Question

After an experiment the following readings were obtained

Cell 1: 198, 201, 204, 207 (all in cm)

Cell 2: 130, 135, 138, 141 (all in cm)

Compare the emf.

Accepted Answer

Imagine that we have a scale with 24 V corresponding to 240 cm.
Therefore, higher value in cm means higher value of emf. As we see,
the emf (electromotive force) of the second cell is higher.
