Electronic Laboratory Practise - Lab Report Example

After setting the oscilloscope time-base to 50, graphs were shown in the oscilloscope for ground, AC and DC. The figure (2) displays the spectrum of DC signal obtained with a peak to peak voltage of 10.3V and root mean square voltage of 3.545V when the oscilloscope was set at a time base of 100 microseconds Figure (3). DC graph on the oscilloscope when connecting the time base to 50              From the graph, the root mean square voltage was determined to be 61mV while the peak to peak voltage was 300mV.

  The root mean square voltage was 6.996V and a peak to peak voltage of 10.3V at a time base of 100 microseconds. Switching to ground gives a straight line that represent the position of 0 Volts. Toggling the signal to DC gives the distance of the signal from the ground. Switching back to AC removes the DC component and show oscillations around the ground marker as illustrated in diagrams on the appendix.             In conclusion, majority of the objectives were satisfied.

The potential divider and the current divider which are critical components of electrical circuits were demonstrated. Practice on the application of digital multimeter and oscilloscope in measurement of current, voltage and resistance was also achieved. Error estimation was also described in some cases and the impact it has especially in understanding electrical circuits. Ohms law that relates I, V and R, was equally applied in conceptualizing the operation of voltage and current dividers respectively.

Thus, the knowledge acquired is necessary in design, construction, analysis and interpretation of electrical circuits.
