Q2 of 6 Page 27

A battery is to be formed by joining 3 dry cells them with connecting wires. Show how you will connect the wires by drawing a diagram.

To form a battery the voltage sources i.e. the dry cells must be connected in series because voltage source when connected if connected in series gives the same voltage.



V1 V2 V3


→ Represents a single cell.
