As long as there is voltage, there will be current; do voltage and current always exist simultaneously? Unless it is a vacuum

Even if the exterior of an electrical appliance is grounded and a person does not get an electric shock when touching it in the event of a leakage current, this does not mean that no current flows through the body; it simply means that the current flowing through the body is too small to be felt by the person. Is such an understanding and statement the accurate one?
Non-resistive circuits, such as inductive circuits
Current can only flow if there is a circuit; learn about birds perching on high-voltage lines
Then you might as well say that there is still current in the absence of a short circuit, only it’s very weak. One could even go further and say that current flows between any two objects with different potentials? Current is generally defined as the movement of electrons; it depends on whether you want to get too technical about it. Perhaps saying it this way better fits our broader understanding: to measure the voltage between two objects, current must flow as a result of conductivity. What do you think?~
These are two parallel circuits; the resistance of the human body is much greater than that of the grounded circuit, so the current flowing through the human body is extremely small and can be ignored.
Because the current flowing through the bird is very small, it simply can’t feel it
How does a vacuum transmit electricity?
Current is the movement of electrons; can’t electrons move in a vacuum?
Do electrons break free and fly out of the conductor? Roaming in a vacuum?
