(Voltages and currents used with PNP transistors will have the same shape, but will have the opposite polarity) CE characteristic curves are plotted by setting the base current (I B) to some specific value, and then measuring the change in I C as V CE

Chapter Seven ALTERNATING CURRENT - NCERT
ncert.nic.involtage and current phasors on vertical axis, i.e., vm sin ω t and im sin ω t, respectively represent the value of voltage and current at that instant. As they rotate with frequency ω, curves in Fig. 7.4(b) are generated. From Fig. 7.4(a) we see that phasors V and I for the case of a resistor are in the same direction. This is so for all times.
Analyses of Lateral Loaded Piles with P-Y Curves ...
connect.ncdot.govcurves used. The selection of adequate p-y curves is the most crucial problem when using this methodology to analyze laterally loaded piles (Reese and Van Impe 2001). • P-Y curves in literature are empirical in nature. Need to carefully review applicability of the selected curves.
