This is a cheap DC Voltage Doubler Circuit diagram, which requires a few components and will deliver 10V from a 5V power supply. If the oscillator must be built from a non-functional gate then is ...
While most readers are knowledgeable about voltage doublers, here is a discussion about how to use them in unusual ways to enhance power supply circuits that might be otherwise limited in features.
A design of voltage doubler circuit has been studied in context of electromagnetic energy harvesting using 28 nm FD-SOI technology. After analysis of the operating constraints of the circuit, the ...
Consider KVL for a moment. It must be the case--in the circuit you provided--that the voltage drop across the resistor is the same as the voltage provided by the battery. Effectively the voltmeter is measuring both of those voltages because they are identical. Note also that the ideal voltmeter does not allow any current to pass through it.
I realize connecting two different voltage sources in parallel is a contradiction (in an ideal circuit). But if I were to connect this in practice and measure the voltage across points A and B, what
The voltage rating is just an upper limit, which must never be exceeded in a functional circuit. Replacing a capacitor with something that has a higher voltage rating is always safe.

We say that voltage is like pressure, or like gravitational potential energy, because we're trying to draw an analogy to something that you can see or feel (because you can drop a rock on your toe, or feel the pressure in a balloon when you blow it up). What voltage is gets abstract (hence the analogies).
