Answer:
Here is my series circuit diagram with a battery, one resistor, one bulb, and one switch:
Attachment: Picture credit goes to BYJU'S
The circuit is a series circuit because the current flows through all of the components in the circuit in a single path. The battery provides the voltage, the resistor limits the current, the bulb lights up when current flows through it, and the switch controls whether or not the current flows. Note: This is for additional information only.
Part 2 Questions
1. Ans:
The circuit I created is a series circuit. In a series circuit, the current is the same through all of the components. This means that the current that flows through the resistor will also flow through the bulb and the switch.

2. Ans:
If I were to add two more resistors to my circuit, but my voltage source stayed the same, the current in the circuit would decrease.
This is because the total resistance of the circuit would increase, which would decrease the current according to Ohm's law (V = IR).
For example,
If the original current in the circuit was 1 amp, and I added two resistors with a resistance of 1 ohm each, the new current would be 0.5 amps.
The decrease in current would have a negative impact on the device that the circuit is powering.
For example,
If the device is a light bulb, the light bulb would be dimmer.

3. Ans:
The role of the switch in an electrical circuit is to control the flow of current.
When the switch is open, no current can flow through the circuit. When the switch is closed, current can flow through the circuit.

4. The path of electric current through my circuit is as follows:
- The current flows from the battery to the resistor.
- The current then flows through the bulb.
- The current then flows through the switch.
- The current then flows back to the battery.
