Follow the instructions carefully!

1. Ensure only the 'Labels' option is checked

2. Play around with the circuit components to form a simple closed circuit!

3. Attach a voltmeter to the ends of the circuit.

In my circuit, the potential difference across the light bulb is 18.0V! Do you know why? 🤔

4. You can detach components from one another by first clicking on the dotted circle that connects them.

Thereafter, you click on the 'scissors' icon

5. If you would like to remove any component, simply click on it and click the 'bin' icon at the bottom

1. Set up a circuit using the PHET simulation in accordance with the circuit diagram above.

2. Turn on the switch and record the value of the current as shown on the ammeter.

Comment, in this section, the value of the current found!

1. Add another resistor in parallel as shown in the circuit diagram above.

2. Record the value of the current as shown on the ammeter.

3. Repeat steps 1 & 2 until you have five resistors in parallel with one another.

Comment, in this section, the value of the current found for each additional resistor (e.g. For 2 resistors, current is 2.0A)

1. Input the values you found into the respective columns. The corresponding points should appear on the graph.

Remarks: The I values in the picture are random. I've put them in to demonstrate how the points will appear.

2. Click on the icon at the top left of the table

# data[].attributes.body
3. A line should appear on your graph which cuts through your data points.

This is the best-fit line according to Desmos!

Comment, in this section, the formula found and state the gradient of this line

# data[].attributes.body
Using the gradient found could you determine the resistance of each resistor?

Verify your solution by checking on the 'Values' option at the top right corner of the simulation

Write down your biggest takeaway from this lesson!

# data[].attributes.body
At the end of the lesson, I am able to:

(i) Accurately setup a parallel circuit

(ii) Apply my understanding of parallel circuits to find the resistance of each resistor

(iii) Analyze the results from my graph to find the resistance of each resistor
