W6. (a) Redraw a detailed sketch of VBC and draw in a horizontal line corresponding to the DC value you measured in Step BP3. Does this DC value appear to represent the average value of the function depicted in your sketch of VBC or something else? Explain. (b) Does your sketch of VBC represent an AC voltage, a DC voltage, both, or neither? Justify your answer. BP3. Measure the voltage between Points B and C (VBc ) using the oscilloscope, and the AC and DC voltages using the DMM. BP4. Sketch the patterns shown on the oscilloscope.
