Question

How can I represent a schematic diagram of a circuit for three D-cells placed in a battery pack to power a circuit containing three light bulbs in parallel?

Answer 1

Hint:We will be constructing a circuit with the help of the given data. We will also be keeping in mind the basic knowledge of circuit construction such as parallel combination and series combination.

Complete answer:
First of all, we will draw a schematic diagram of the circuit.

Now as we can see from the figure that even though it is not mentioned in the problem, it is a good practice to connect all the cells in a series. And it is also a good practice to connect switches in your circuit as for safety measures. We can notice that a switch is connected in series with each of the three bulbs as a safety measure or it can also be used to connect or disconnect bulbs according to our needs.

It is also a good practice to connect all the bulbs in a parallel connection as we all know that the voltage across the bulbs will be the same in the parallel combination. Whereas, if they are connected in series, the voltages may divide and the bulb may not glow at its full potential. It is also to note that the voltage across the bulbs will be the same as the voltage across the battery pack. Here, the battery pack consists of three D-cells.

Note: While drawing a circuit, it is very important that all the wires are connected properly to the following electrical component. All the symbols of each and every electrical component should be drawn correctly without any mistakes. The positive and negative terminals of each and every component should be mentioned properly.
