    Hello :) I'm new and have a problem...
    Why do we connect the ammeter in series and the voltmeter in parallel?
    He doesn't quite understand it :)
    If there is anyone who could help me, please do :)
    Urgent !! :)

    The current flows, so you have to join the ranks and measure what is flowing. Voltage is the potential difference between two points, so we connect a voltmeter to them creating a parallel connection.

    Could you extend it somehow? :)

    If I'm not mistaken, the ammeter has a resistance similar to a wire, so if we connected it in parallel (without adding any resistance to the branch) it would burn, because it would cause a short circuit. In addition, we want to measure the current in a given branch with it. The voltmeter, on the other hand, has infinite resistance (creates a gap), so it is connected in parallel to check the potential difference between two points (any voltage drops, etc.).

    Or maybe a colleague would look into literature like this?
    It seems to help... :)

    Lukasss_93. Do you know the difference between current and voltage?

    yes.. current is the movement of charge carriers under the influence of applied voltage and voltage is the difference of potentials conditioning the flow of current

    Well, since you know that current is the movement of electric charge carriers. That is how water flows in a tap.
    In order to measure the current, we need to pass this current through the ammeter. Similarly, if you want to measure the flow of water, turn on the flowmeter in series with the installation.
    And when measuring voltage (water pressure) no current flow is necessary.

    The ammeter is a water meter according to the Iony analogy - it must be plugged into the pipe ...

Topic summary

The discussion centers on the fundamental principles of connecting ammeters and voltmeters in electrical circuits. An ammeter is connected in series to measure current, as it needs to be part of the circuit to gauge the flow of charge carriers. In contrast, a voltmeter is connected in parallel to measure voltage, as it requires no current flow and has high resistance to avoid affecting the circuit. The analogy of water flow is used to explain these concepts, where the ammeter is likened to a water meter measuring flow, while the voltmeter represents water pressure measurement.
