Electronic – How does a NOT gate generate power?


I know that a NOT gate always inverts its input.

When the input is "ON" I can imagine the gate stopping the flow of current.

But how does the gate generates flow of current when the input is OFF?

Please could you explain how this happens as simply as possible, I'm new to electronics 😉

Logical gates are electronic circuits having their power supplies in addition to the logical IO. If you look at the ICs implementing the NOT gate, you will notice Vcc and GND pins for that purpose. On logical diagram you are not usually seeing them, because they are unnecessary for the logical description.
