Update with Complete Solution
RNT1- Task 4 Electromagnetism: Circuits A1) The first experiment I conducted is a functioning series electric circuit with two light bulbs as resistors. I did this by connecting the first resistor to the positive side of the battery. Then I connected the second resistor to the negative side of the battery. Lastly, connected an alligator clip to both bulbs to allow the simple series circuit to push electrons through the entire circuit. Below, I have attached a photo of the experiment and an illustration utilizing symbols of the experiment.
In this simple series circuit, the AA battery acts as the power source, providing the voltage that pushes electrons through the circuit. When the circuit is closed, current flows from the positive terminal of the battery through the first light bulb, then to the second light bulb, and finally back to the negative terminal of the battery. The light bulbs, which serve as resistors, convert electric energy into light energy, causing them both to light up. The brightness of the bulb depends on the total resistance in the circuit. If I were to add more bulbs, the overall current flow would be affected, influencing the brightness of the light emitted. A2) If one bulb is removed from the standard circuit, the circuit becomes incomplete. This interrupts the flow of electric current throughout the entire circuit. As a result, the voltage in the whole circuit will drop to 0 because the circuit becomes open, interrupting the flow of electricity. Consequently, the current in the circuit will also drop to 0 as there is no complete path for the current to travel from the battery. The total resistance of the circuit will technically remain the same. However, since the circuit is open, the current cannot flow, as a result, both light bulbs will not emit any light. As the removal of one bulb effectively causes the entire circuit to fail, resulting in no brightness from any of the resistors. B1) The second experiment I conducted was a functioning parallel electric circuit. I did this by using two light bulbs and one AA battery. I started by connecting the battery's positive and negative wires to the first light bulb, then I used two alligator clamps to attach the second light bulb on each side. The parallel circuit caused the light to shine brighter than in the first experiment. Below, I have attached a picture of the second experiment and a diagram of the experiment utilizing symbols.
