Where do you get this?

As to "sort of.." you better believe it.
What do you think stores the program in your processor?
Charge (voltage) consisting of electrons quantum-tunneled into the gate of a mosfet.
Voltage, is simply a measurement of the relative charge between two objects.
It is entirely measureable without ANY current flow at all.

Current can exist without voltage at all, in fact it does all the time.
Current is electron flow.
Take a plate of lead, cool with liquid helium, and drop a magnet on it.
The resistance of the lead is literally zero ohms, and the current induced by the magnet sets up an opposing magnetic field, that supports the magnet.
