Year & Section: Group no: Leader: Members: Experiment 1: RMS Values of Voltage and Current Objective: 1. To investigates the relationship between the peak and rms values of different periodic signals. Materials: 1. Function generator (Mode: Sine, Triangular and Rectangular) 2. Oscilloscope (Channel A: 1V/div, Channel B: Off, Time base: 5ms/div, Mode: X/T, AC, Trigger: Channel A / rising edge / pre-trigger 0%) 3. 100-ohm resistor 4. Voltmeter 5. Ammeter Procedure: 1. Assemble the circuit as shown in figure 1. 2. Use the function generator as source. (sinusoidal mode) Figure 1. Circuit Diagram 3. Determine the peak voltage value using oscilloscope and use it to calculate the rms value. Record the value in Table 1. 4. Close the oscilloscope and open the voltmeter virtual instrument to measure the RMS value and compute the peak value. Record the results in Table 1. 5. Close the voltmeter and open the ammeter virtual instrument to measure rms and compute the peak current. Record the results in Table 1. 6. Increase the frequency to 1kHz. 7. Switch the function generator to rectangular mode, then record the results in Table 2. 8. Switch the function generator to triangular mode, then record the results in Table 3. Note: refer to this for formulas converting rms to peak or vice versa for sinusoidal, triangular and square wave. https://wp.optics.arizona.edu/mnofziger/wp-content/uploads/sites/31/2016/08/AVG-and-RMS-Val ues-of-Periodic-Waveforms-2012.pdf Data and result: Table 1.
