$5.$ Part Four: a comparator application and parameter sweep

A$.$ Simulate the temperature alarm in exercise $42,$ shown here. Choose a convenient value for to show for the variable resistor $($first$,$ create the resistor, then change its symbol to include the variability arrow$).($Note that although the $5$ V and $-5$ V supply voltages are indicated on the sides of the op amp symbol associated with the opposite$-$polarity input terminal, they are still the $\backslash ($ V$^\{+\}\backslash )$and $\backslash ($ V$^\{-\}\backslash ),$ respectively.
