If cells are joined in parallel, they have _______.
- same current
- same potential difference
- same resistance
- same power
Answer: 2. same potential difference
Explanation: Components connected in parallel provide alternative pathways for current flow. When cells are connected in parallel, the total voltages that they provide does not change. For example, when two or more 2 V cells are connected in parallel, they still provide a total voltage of 2 V.
