11 Balanced Three-Phase Circuits Assessment Problems AP 11.1 Make a sketch: We know VAN and wish to find VBC . To do this‚ write a KVL equation to find VAB ‚ and use the known phase angle relationship between VAB and VBC to find VBC . VAB = VAN + VNB = VAN − VBN Since VAN ‚ VBN ‚ and VCN form a balanced set‚ and VAN = 240/ − 30◦ V‚ and the phase sequence is positive‚ VBN = |VAN |//VAN − 120◦ = 240/ − 30◦ − 120◦ = 240/ − 150◦ V Then‚ VAB = VAN − VBN = (240/ − 30◦ ) − (240/ − 150◦ ) = 415.46/0◦ V

Density (Linearized plot) TA: Blue Rex rex Group Members: Billy and Mandy Tuesday; 1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then
