9.4 Assignment 3: Investigating Electric Current in a Circuit Overview In this activity, you will review the effects of resistivity and voltage on the electric current in a circuit. Materials Needed / Resource Bank 0 PhET Simulation: Circuit Construction Kit: DC Instructions Answer the below questions one at a time. Make sure to read directions within each question carefully. Questions 1. a) In your own words, describe what resistance is and how this affects the electric current in a circuit. b) In your own words, describe what voltage is and how this affects the electric current in a circuit. 2. Follow the directions in the below procedure to investigate where resistance occurs in an electric circuit. Procedure 1. Go to the webpage PhET Simulation: Circuit Construction: DC. Choose the \"Intro\" option. User tips: - To add things to the simulation, click on the items listed on the left side. - To remove things from the simulation, click on the item. It should have a yellow highlight around it, and a trash button "*1 shows up at the bottom of the page. Click on the trash button to delete the item. - To disconnect pieces, click on the junction between the two pieces. A scissor button i9 shows up. Click on the scissor to disconnect. 9395'?\"l 10. qu estion*** Create a closed circuit using one battery, two wires, and one switch in a single loop. Close the switch. Record your observations. You can open the switch any time you want to stop the electric current momentarily. l I] Advanced Click on the \"Advanced\" button on the right side. Increase the wire resistivity. Record your observations. Change the wire resistivity back to \"tiny\". Increase the battery resistance. Record your observations. You should have observed that the electric current moved very quickly and the battery was on fire when the circuit was made of just wires and a battery, and there was tiny resistance in the wires and battery. Explain why this did not occur when you increased the resistance in either the wire or battery. Change the wire and battery resistance back to \"tiny\". Add a resistor '11]- " to the circuit. Record your observations. Switch the resistor out with a light bulb to the circuit. Record your observations. Based on your observations in this simulation, what affects the speed at which electric current runs through the circuit? Where does the electric current experience resistance throughout a circuit? ***Do not close or reset the simulation. You will continue with more directions in the next 3. Follow the directions in the below procedure to investigate how voltage affects the electric current. Procedure Create a closed circuit using one battery, one light bulb, two wires, and a switch in a single loop. Make sure the wire and battery resistance are set to \"tiny\". Note the direction the electric current is moving. Click on the battery. A set of options should pop up at the bottom of the page. Click on the In \\- I] u battery switch button I --J ,this will flip the battery. Click it a few times to see how this affects the electric current and the lightbulb. Record your observations. Voltage 9.0 volts There should also be a voltage bar E I] E] in the options that popped up when you clicked on the battery. Use this to increase the voltage. Record your observations about what happens to the electric current and the light bulb as the voltage increases. ***Do not close or reset the simulation. You will continue with more directions in the next qu estion*** 4. Follow the directions in the below procedure to investigate how capacitor affects the electric current. Procedure 1. Your circuit should still be a single loop made of one battery, one light bulb, two wires, and one switch. Set the voltage of the battery to a high voltage by clicking on the battery and adjusting its voltage. Choose any high voltage amount above 100 V. Fiecord the voltage of the battery. 2. Click on the down arrow in the items list to find the second resistor item that looks like this: . Add this resistor to your circuit. 3. Click on the resistor. A set of options should pop up at the bottom of the page. Increase the resistance of the resistor. Record what happens to the electric current and the light bulb as you increase the resistance. 4. Look for the resistance level at which the electric current seems to finally stop moving. (Note: it never completely stops moving) What amount of resistance did you need to set for the current to ALMOST stop moving
