Ammeter in Series & Voltmeter in Parallel Connection: Understanding the Science

Hello everyone

I'm new and I have a fairly simple question that I can't find the answer to Why is the ammeter connected in series and the voltmeter in parallel? Please help me quickly. Thank you in advance.

Hello .
The case is as follows. We connect the voltmeter in parallel, because it has a very high internal resistance. Connected in series, it causes such a large voltage drop that devices connected after it would receive a voltage equal to or close to 0V and its operation would be impossible. The ammeter has a very low internal resistance and is connected in series in the circuit. The voltage drop across it is minimal and connected in parallel to a circuit will cause a short circuit in that circuit. It can't be explained any simpler.
Regards

In simple terms (more or less): an ammeter is a voltmeter that measures the voltage drop across a built-in resistor and calculates the current using Ohm's law. And that's why it must be connected in series (because the current must flow through the resistor). A voltmeter measures the voltage drop between two points, so it must be connected in parallel.

An ammeter measures the current flowing through a given section of a circuit, and a voltmeter measures the voltage, i.e. the difference in potential between two points in the circuit.

Thank you very much for the detailed answer and best regards. You helped me a lot
