Click on Tircuit Simulator", Online link: I) Build the following circuit with one lightbulb, two resistors, and one battery. Click on the lightbulb and change its resistance to 300, click on one of the resistors and change its resistance to 20n as shown in the diagram. (You can view the parameters when you click on "Values".) DL4 20. 2) Insert an ammeter into your circuit and write down the current measurement. 3) Measure the voltage drops across each resistor and lightbulb using a voltmeter and record these values. 90 v 4) Measure and record the voltage drop across the two resistors and the lightbulb combined S) Verify Kirchhoff s loop rule for this circuit. Be careful With signs for voltages across the battery and resistors. Check With your TA that your circuit and measurements are correct before moving on to the next part. B) Calculate the Resistances 6) Make a schematic drawing Of this circuit using the symbols shown here. Remember, ammeters are "in series" in the circuit and voltmeters are wired "across" a particular element. 7) On the drawing of your circuit label the current and the voltage drops you measured in 2) and 3). 8) Calculate the value of the resistance of each resistor using the relevant equation at the top of the page and your measurements from 2) and 3). Confirm that these calculated values agree with the actual resistance values. 9) Calculate the value of the total resistance of the string of resistors the voltage measurement in 4). 10) What is the relationship between the measured voltage drop across the entire string of resistors and the separate voltage drops? 11) What is the relationship between individual resistances and the total resistance calculated in 9)? battery resistor voltmeter ammeter Whole Class Discussion Unit S: Flow, Transport and Exponential Change Physics 7B DL4 DL4 Activity 5.11 Making Sense of Simple Circuits II A) Use the Complete Energy-Density Model I) For this same electrical circuit consider that the voltage of the battery is 6 Volts, i.e., E = 6 V. and the light bulb has a resistance R 4.0 n, Use these values and the annronriate form of the previOUS Dashboard Calendar 00 To Do Notifications Next Inbox
