Question: Using the reference marks in Figure 161, calculate the average and reactive power for the following voltages and currents. (a) t = 168 cos377t +

Using the reference marks in Figure 16–1, calculate the average and reactive power for the following voltages and currents.

(a) υðtÞ = 168 cosð377t + 45ÞV, i ðtÞ = 0:88 cos 377t A

(b) υðtÞ = 285 cosð2500t + 68ÞV, i ðtÞ = 0:66 cos 2500t A

i(t) Source v(t) Load FIGURE 16-1 A two-terminal interface.

i(t) Source v(t) Load FIGURE 16-1 A two-terminal interface.
