Lesson Worksheet: NOT Gates Physics
In this worksheet, we will practice determining the input and output of NOT gates in logic circuits and completing truth tables for NOT gates.
A kettle is used to boil water. In the kettle, the heating filament is connected to a thermometer by a NOT gate. This is shown in the diagram below.
The thermometer measures the temperature inside the kettle. The heating filament turns off if the temperature inside the kettle is higher than .
When the temperature inside the kettle is lower than , the input to the NOT gate is 0. What is the output of the NOT gate when the temperature in the kettle is higher than ?
