Answer:
1. In a parallel circuit with three dry cells as a source of energy, how are the wires connected to the dry cell? why?
First of all you need to remember a very important thing, two voltage sources can never be connected in parallel, they should be always connected in series.
This is bcoz voltage in parallel is always the same. Vice-versa is for current source, Two current sources should always be connected in parallel.
Now as for the question,
A dry cell is a voltage source hence, they need to be connected in series to each other as shown in the attachment, they are connected in series and the net potential produced by the three dry cells would be,
V1 + V2 + V3
3V if the potential of the three cells are the same.
2. Based on your drawing give one advantage of the parallel circuit.
Parallel circuit
What are the advantages and disadvantages of parallel circuit?
Advantages
- All loads in parallel connection are directly connected to the voltage source.
- In parallel circuit, even in one of the light bulbs is damaged, all other light bulbs will function since the flow of current is not entirely interrupted.
- Individual load in a parallel circuit is easy to control.
- All light bulbs and appliances at home are connected in parallel. Switching off some appliances does not affect other appliances
Disadvantage
- Overloading may happen if appliances are simultaneously used at home
- A parallel connection is difficult to install, maintain, and repair since large volume of conducting wires is needed. When problem in the connection occurs, it is difficult to identify which loop among the many loops does not work.
- It requires the use of several conducting wires of varying sizes.

Stay safe, bye.
