Question

The time-domain expressions for three line-to-neutral voltages at the terminals of a Y-connected load are vAN=276cos(?t?45?)V, vBN=276cos(?t?165?)V, vCN=276cos(?t+75?)V. Part A What are the time-domain expressions for the line-to-line voltage vAB? Suppose that vAB(t)=VABcos(?t+?AB), where ?180?<?AB?180?. Determine the values VAB and ?AB. Express your answers using three significant figures separated b What are the time-domain expressions for the line-to-line voltage vBC? Suppose that vBC(t)=VBCcos(?t+?BC), where ?180?<?BC?180?. Determine the values VBC and ?BC. What are the time-domain expressions for the line-to-line voltage vCA? Suppose that vCA(t)=VCAcos(?t+?CA), where ?180?<?CA?180?. Determine the values VCA and ?CA.
