Consider an ac circuit consisting of a power supply and a resistor. if the current in the circuit at time t is i, sin wt, then the
power delivered to the resistor is 1, rsinº wt, where r is the resistance. express the power in terms of cos 2wt.
c. p=1,r+1,ʻr cos2wt
a p=*r+* 1, r cos 2wt
b. p=1,38-rocos 2wt
d.
p=1/r-10r cos 2wt
