Parallel DC circuits - Lab Report Example

To study various waveforms on the DSO, the 3MHz Function Generator (TG300 Series) was connected to CH1 of DSO (Tektronix) using BNC leads. A sine wave of 1 kHz frequency and a root mean square voltage of 1.4145V was displayed on the screen. The period of the sine wave was determined using equation 1 in the introduction. Furthermore, the peak to peak voltage of a sine wave was measured and recorded as required. The waveforms and its FFT graphs were then printed out using the PC communication software.

            Similarly, a square wave with parameters 2 kHz frequency and 2Vpeak was shown on the screen. The period of the waveforms and the peak-to-peak voltages were determined. The FFT graphs were printed out as required. The above procedure was repeated for 1.5 kHz, 2Vpeak triangular waveform, and a similar analysis was done and recorded.             A parallel resistor circuit was drawn using the NI Multisim software available on desktop PC.

Using the Multisim virtual ammeter available on the software, current on the branches and the total current from the battery were measured and recorded. Using the current and the voltage supply from the battery the power delivered by the battery was calculated as shown in the results below. A 1 kilo ohm resistor was then connected in series with a parallel combination that was created, and the above steps were repeated.
