Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
When there is a break in a circuit, an ammeter will read zero. Kirchoff's current law states that the current at every point in a series circuit is the same. Since a break has (effectively) infinite impedance, its current will be zero, and so will be the current through the ammeter.
The ammeter will read zero (0) because no current is flowing. An ammeter reads the flow of current in a curcuit. When there is no circuit, there is no current (amperage) flow.
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
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.
That's the purpose of the "ammeter".
"ammeter"
An open switch in a circuit will stop all current flow so the ammeter should read zero amps.
How do you connect an ammeter to a circuit?
An ammeter is always connected in series in the circuit.
An ammeter measured how many amperes of current are flowing in an electrical circuit.
An ammeter measures the electrical current in something. A digital one is calibrated to display through the shunt and convert information from the analog model.
connect ammeter in series with load.
The ammeter measures the amount of current in a circuit.
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
The ammeter does affect the flow of current in a circuit, however, the resistance of the ammeter is so small in comparison to the circuit that the effect is negligible. It is connected in series.
Series connect it within the line of the circuit for which you are interested in measuring the current flow.More detailSince we measure the flow of current IN the circuit, the ammeter must be connected in series with the part of the circuit for which you are interested in measuring the current flow.One of the ammeter's terminals must be connected to a point of the incoming current flow and its second terminal must be connected to the point of on-going current flow. To do this, cut the relevant circuit wire and connect one terminal of the ammeter to each end of the cut.
It measures the current.
To measure current in circuit
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
