$||$ EG $210-1$ PROGRAM $05$ DESCRIPTION

Program Background and Description

This program will simulate collecting electrical parameters from an electrical circuit. The parameters will need to

be collected multiple times therefore the program must loop. The program will collect exactly $10$ value sets. Each

loop will collect a resistance $(R)$ value, a current $($I$)$ value, calculate power $(P)$ with the equation $P=I^2**R,$ and

add this loop's power to a summing variable. After the loop, use the summing variable to complete the average

calculation $($average power $=\frac{\text{s}\text{u}\text{m}of\text{p}\text{o}\text{w}\text{e}\text{r}\text{s}}{\text{n}\text{u}\text{m}\text{b}\text{e}\text{r}of\text{p}\text{o}\text{w}\text{e}\text{r}\text{s}\text{c}\text{o}\text{l}\text{l}\text{e}\text{c}\text{t}\text{e}\text{d}})$ and print the desired outputs to the screen.

Part of the desired output is an indication of safe or unsafe. Resistors turn the electrical power they receive into

heat. If a resistor receives too much power for too long, it has a possibility of melting the resistor and causing

permanent damage to other components in the circuit. Generally, the resistors in the PCC electrical lab have a

$0\mathrm{.}25$ Watt rating; therefore powers equal to or lower than $0\mathrm{.}25$ are safe. To print the correct word$($s$)$ to the screen,

an if statement must be used to determine whether the average power is safe or unsafe.

Resistances are only allowed to be positive values; so if a negative value is input into the program, it was done in

error. Instead of sending an error message, the program will simply remove the sign from every resistance input.

The functions $\frac{?}{abs},\frac{f}{a}bs,$ and fabs $f$ will remove any negative sign from a value and positive values will be

unchanged $($because the positive is not shown on the front of the number$).$ Pages $250$&$251$ in the textbook

shows how to implement the functions in code, the difference between the functions, and the required library for

each.
