Lab # 2 ENG 220-001 Name: Date: AC measurement Introduction to the Oscilloscope ENG 220 LAB -2 Objective: At the completion of this experiment, you will be able to: Operate an oscilloscope and DMM. Use an oscilloscope to measure DC and AC voltage and convert the AC measurement to Vpeak and Vrms. 1. Construct the circuit. Calculate the DC IR drop for each resistor. Then measure using the DMM and record the DC IR drop for each resistor. Calculated: V2.2k= KVL V4.7k= V10k= V4.7k= V10k= VT= V2.2 + V4.7 + V10 Measured: V2.2k= KVL VT= V2.2 + V4.7 + V10 2. Using an Oscilloscope measure and record the DC IR drop for each resistor. V2.2= KVL V4.7= V10= VT= V2.2 + V4.7 + V10 Which instrument gives you better measurements? (Explain) 3. Construct the circuit. Calculate the AC voltage drop for each resistor. Then measure using the DMM and record the IR drop for each resistor. Calculated: V2.2= KVL V4.7= VT= V2.2 + V4.7 + V10 V10= Measured: V2.2= KVL V4.7= V10= VT= V2.2 + V4.7 + V10 Calculate Vpeak and Vpeak-peak. for each resistor. What is the relationship between your measured Vpeak and Vrms ? 4. Using an Oscilloscope measure and record the AC IR drop for each resistor. V2.2= KVL V4.7= V10= VT= V2.2 + V4.7 + V10 Calculate Vpeak and Vrms. for each resistor. What is the relationship between your measured Vpeak and Vrms ? Conclusion:
