At t = 5 ms, p = 150 cos2 (60 5x10-3) = 150 cos2 (0.3 )

p = vi = 5 cos (60 t)[6 + (50/(60 )) sin (60 t)]
At t = 5 ms, p = 5 cos (0.3){6 + (50/(60 )) sin (0.3 )}
=5(0.58779)(6+(0.26526)(0.80902)) = 18.264 watts
P.P.1.6 p = v i = 115 x 12 = 1380 watts; w = p x t
W = 1380x24 = 33.12 k watt-hours
, P.P.1.7 p1 = 5(–45) = –225 w
p2 = 2(45) = 90 w
p3 = 0.12xI(20) = 0.6(25)(20) = 60 w
p4 = 3(25) = 75 w
Note that all the absorbed power adds up to zero as expected.

p = v0 i = 25 x 103 x (1.6 x 10-6) = 40 mW
P.P.1.9 Minimum monthly charge = $12.00
First 100 kWh @ $0.16/kWh = $16.00
Next 160 kWh @ $0.10/kWh = $16.00
Remaining 0 kWh @ $0.06/kWh = $0.00
Total Charge = $44.00
Average cost = $44/[100+160+0] = 16.923 cents/kWh
P.P.1.10 This assigned practice problem is to apply the detailed problem solving
technique to some of the more difficult problems of Chapter 1.
