Chapter 1, Problem 1.27P

Using the passive sign convention, the voltage across a device is $v\left(t\right)=240\cos \left(314t\right)\text{V}$ and the current through the device is $i\left(t\right)=4\sin \left(314t\right)\text{A}\text{.}$ Using MATLAB, create a short script (In-file) to assign a value to the time variable, t, and then calculate the voltage, current, and power at that time. Run the script for $t=5\text{ms}$ and $t=10\text{ms,}$ and for each result state whether the device is absorbing or delivering power.
