How should the electric lamps in a building be connected ?

Explanation

### Step-by-Step Text Solution:

1. **Understanding the Connection Types**:
- There are two main ways to connect electric lamps: in series and in parallel. In a series connection, the current flows through each lamp one after the other, while in a parallel connection, each lamp is connected directly to the power source.

2. **Advantages of Parallel Connection**:
- When lamps are connected in parallel, they all receive the same voltage. This means that each lamp can operate independently. If one lamp fails (for example, if it fuses), the others will continue to work. This is a significant advantage in a building where consistent lighting is necessary.
