1. Set up a circuit with your power supply and a resistor of R₁ = 9.0 ̐. Sketch your circuit diagram below with an ammeter and voltmeter in it to measure the potential difference across the resistor and the current through the resistor. Now measure and record both the potential difference across the resistor and the current through it and record your values below.
Circuit Sketch
Resistor: R₁ = 9.0 ̐
Current (A): 2.22
Voltage (V): 20.00
2. Drag another resistor into the active and set its resistance to R₂ = 57.5 ̐. Make a series circuit with your two resistors and sketch your circuit diagram below with an ammeter and voltmeter in it to measure the potential difference across R₁ and the current through R₁. Measure and record the potential differences across R₁ and R₂ as well as the current through both resistors. Measure, also, the total potential difference across the set of resistors.
Circuit Sketch
Resistor: R₁ = 9.0 ̐, Current (A): 0.30, Voltage (V): 2.71
Resistor: R₂ = 57.5 ̐, Current (A): 0.30, Voltage (V): 17.29
Total Voltage (V): 20.00
3. Drag another resistor into the active and set its resistance to R₃ = 22.5 ̐. Make a series circuit with your two resistors and sketch your circuit diagram below with an ammeter and voltmeter in it to measure the potential difference across R₃ and the current through R₃. Measure and record the potential differences across R₁ and R₂ as well as the current through all resistors. Measure, also, the total potential difference across the set of resistors.
