Current stops flowing.
A multimeter set to measure current (in amperes) would be used to measure current flowing in a circuit. The multimeter needs to be connected in series with the circuit to accurately measure the current.
the current flowing in will be low
Current in a series circuit is the same throughout the circuit. Voltages are additive. Voltage in a parallel circuit is the same throughout the circuit. Currents are additive.
An amp meter connected in series with the load will show whether or not a current is flowing in a circuit.
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
An ammeter is the instrument used to measure current in an electric circuit. It is connected in series in the circuit and provides a reading of the amount of electric current flowing through it.
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
An Ammeter provides a visual display of the magnitude of the current flowing through it. Ideally, the ammeter does nothing "in the circuit". You don't want your test equipment to change anything going on in the circuit you're measuring.
As long as an electrical power source is connected to itself with electrical conductors of some kind, then a current will flow through it. How much current will depend on the components used in the circuit.
In a parallel circuit, the hypothesis is that when components are connected in parallel, the total current flowing into the junction equals the total current flowing out. Essentially, the hypothesis states that the total current remains constant regardless of the number of parallel paths.
To measure current, you would typically use a multimeter set to the appropriate current measurement range. First, ensure the circuit is off, then connect the multimeter in series with the part of the circuit you want to measure the current flowing through. Turn on the circuit to get a reading of the current flowing through that part of the circuit. Remember to set the multimeter to the correct range for the expected current to avoid damaging the meter.
