- Have a look at your Workbook (activities 17 and 18) and then do the activities here.
Activity 1. Ohm's Law (paper activity 17)
- This is very important. Click on Lab and place a lamp on the right top of the work area. Select the lamp and change its value (the resistance) at the bottom of the simulator. The new resistance is the number of your user name for Learning Apps. For example, if you are tpr2m_16, the resistance is 16 ohms.
- You have to draw the 3 circuits but one by one (Example1, Example2 and Example3). The 3 circuits have the same components: a battery, a lamp, a switch and wires. Leave the switch open.
- First draw a circuit and then place the measuring tool, close the switch and read the measurement .
- Place a voltmeter to measure the voltage across the lamp and an ammeter to measure the current through the lamp.
- Example1: here use a 9V battery and a 3Ω lamp. Is current 3 amps?
- Example2: here use a 3V battery and a 12Ω lamp. Is current 0.25 amps?
- Example3: here use a 1,5V battery and a 100Ω lamp. Is current 0.015 amps?
- When finished, click on PhTE (at the bottom of the page, right) and take a screenshot and download your picture to Descargas. Change the file name by circuit06.png.
- Then upload your picture to your Google Classroom/unit4_1/ICT_Revision.
Extra. Now download the activity in paper. Go to PDF Bob and upload the activity.
- First complete the table (magnitudes and units)
- Then click on Edit tab to upload and paste the picture you have in Descargas (circuit06.png). When finished, export your PDF file (extra1.pdf) and upload it to your Classroom/Unit4_1/ICT_Revision.
- Don forget the sticky note, name and surnames...
Activity 2_1. Ohm's Law (paper activity 18)

- Series Circuit. First make the calculations to find the resistance of each lamp (RL1, RL2 and RL3).
- Then draw the circuit in the simulator below taking into account your calculations.
- Finally check that your results are good by placing an ammeter to measure the current and a voltmeter to measure the voltage drop across each lamp. Leave the ammeter and the voltmeter connected in the circuit.
- When finished, click on PhTE and take a screenshot and download your picture to Descargas. Change the file name by circuit07.png. Then upload your picture to your Google Classroom/Unit4_1/ICT_Revision.

- Parallel Circuit. First make the calculations to find the resistance of each lamp (RL1, RL2 and RL3).
- Then draw the circuit in the simulator below taking into account your calculations.
- Finally check that your results are good by placing an ammeter to measure the current through each lamp and a voltmeter to measure the voltage drop across the parallel. Leave the ammeter and the voltmeter connected in the circuit.
