EXERCISE NO. 3POWER IN DC CIRCUITSObjectives: The objectives of this exercise are to show how resistor power dissipation is related to voltage, current and resistance in a DC circuit.Procedure: ⦁ Connect the circuit shown in Figure 1 using two 1 kΩ resistors in series. The portable multimeter can be used for the voltmeter. The DMM, used as an ammeter, must be connected in series between the power supply and the resistors.Beginning at 0.0 volts, increase the voltage across the resistors in...

I am working on my Physics lab report where it was all about Direct Current Measurement and Ohm’s Law. We had 5 different resistors and had to construct different circuits using a power supply, volt-ohm-milliammeter (VOM) and a digital multimeter to get measurements of resistance, voltage, and current. Nominal values of resistance and tolerance Resistor Nominal Resistance (Ohms) Tolerance (Ohms) R1 680 +/- 68 R2 1000 +/- 50 R3 1500 +/- 75 R4 4700 +/- 470 R5 10,000 +/- 500...
