Using the measured capacitor voltage values draw a capacitor charge curve over the calculated values curve. Using the In your own words, define "RC time constant. Calculate the time constant for the following RC combinations. B·R= 100 K C= .1pE Compare the charge curves drawn in step 8. Was there a signifi- cant difference. Explain. You are using a pulse circuit to create a given frequency. You want to increase that frequency. What could you do to the RC circuit to make the frequency increase? Your TV picture rolls. You know that the vertical oscillator cir- cuit produces the pulse to synchronize the picture. It must have a component that has changed values. You check the frequency and it is too slow. Has the R or C increased or decreased in value to make the oscillator pulse too slowly?
