How much electrical current is passed through an ammeter in a time of 6 seconds if the ammeter reads 1.8 amps?

1.8 amps of current passed through. I'm assuming you meant electrical charge however, in which case 1.8 A * 6 s = 10.8 C of charge passed through, where C stands for Coulombs. That is equivalent to roughly 6.74 X 1019 electrons passing through.

Does an ammeter measure current?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.
What are the function of ammeter?
The purpose of an ammeter is to sense and display the magnitude of the current flowing through it. When connected in series with a branch of an electrical circuit, the meter displays the magnitude (and direction) of the current in that path ... which you can't otherwise tell just by looking at the circuit.
Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
How does an ammeter work?
An ammeter is a low voltage voltmeter in parallel with a small resistance resistor. Current flow through the resistor creates a voltage drop across it which is then measured by the voltmeter.
Where is the best place to put an ammeter in the circuit to measure the current going through the light bulb?
Since (by Kirchoff's current law) the current in a series circuit is the same at every point in the series circuit, it does not matter where you place the ammeter.
What are the functions of an ammeter?
An ammeter measures the amount of electrical current flowing through a conductor.
What is ammeter used for?
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.
What does a Clamp-on ammeter measure?
An ammeter measures the amount of current flowing through an electrical circuit. It measures amperage.

How do you calculate ammeters?
An ammeter is an instrument that measures electrical current as it travels through a conduit. Amperes are what the measurements that are are measured aree called.
How do you measure electrical current flow in a copper wire?
Electrical current flow in a copper wire is measured with an ammeter. It is either clamped onto the wire or attached at one end to monitor the amount of current moving through the wire.
Why shunt resistance must be small in ammeter?
An ammeter has to measure to current flowing through the circuit. Resistance offers an obstruction to the current flow. So, if the resistance of an ammeter is large , the current measured by the ammeter will be quite less as compared to the actual amount of current flowing through the circuit which is undesirable. If ammeter has zero resistance , then it will give the exact value of current. But this is not practically possible because every material has some value of internal resistance which we can't control. For this reason , ammeter must have small resistance
What will an ammeter show if the circuit is broken?
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.
What happens to an ammeter when there is a break in a 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.
Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
