I was reading about SR Latches and this very weird (and silly) question popped up in my head.
Here, when A and B is 0, then Q is 1.
Suppose that this NOR gate is lying in air, not connected to any power supply. Then as there is no potential or current passing through A or B, we can say that the inputs are 0 and 0. Then according to the truth table, Q must be 1! How is that even possible? What does it even mean?

The truth table is only true when there is power to the device.
Without power, a NOR gate is a NON-gate, or NOT-A-gate.
