A voltage source v s is connected <strong>ac</strong>ross a 4-Ω<br />
resistor. Find <strong>th</strong>e average power absorbed by<br />
<strong>th</strong>e resistor if v s equals (a) 8sin200t (b)<br />
8sin200t − 6cos(200t − 45°) V. (c) 8sin200t −<br />
4sin100t V. (d) 8sin200t − 6 cos 200t − 45° −<br />
5sin100t + 4 V.
