6. If the potential of the battery is 5V and the potential difference across one lamp is 2.6V, what is the potential difference (in volts) across the other lamp? (1dp)

The potential difference across the other lamp can be calculated by subtracting the potential difference across one lamp from the total potential of the battery.

Step 1: Identify the total potential of the battery and the potential difference across one lamp. In this case, the battery potential is 5V and the potential difference across one lamp is 2.6V.

Step 2: Subtract the potential difference across one lamp from the total potential of the battery.

Calculation: 5V (battery potential) - 2.6V (potential difference across one lamp) = 2.4V

So, the potential difference across the other lamp is 2.4V.
