What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current though the resistor?

That depends on the quality (price) of the meter.
Ideally it should have no effect.

What happens to the ammeter reading if resistor is removed?
Opening any circuit will stop the current from flowing.
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 are the disadvantages of ammeter?
The inconvenience of an ammeter is that it needs to be placed in the line in which you want to measure the current; for production circuits, this is often inconvenient or impossible, so usually the current in a circuit is derived by measuring the voltage drop across a resistor.
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.
How to measure current?
Current in a circuit can be measured by using a device called ammeter that is always connected in series in the circuit in which current is to be measured.
What happens to the ammeter reading if resistor is removed?
Opening any circuit will stop the current from flowing.
What job does the ammeter do in the circuit?
The ammeter measures the amount of current in a circuit.
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 will a ammeter indicates if it is connected in parallel?
Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
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 is the 'job' of an ammeter in a circuit?
It measures the current.
Why is voltmeter is connected in parallel and ammeter in series?
Because its function is to measure the current, i.e. the amount of electrical flow in the circuit, and this require that the current flows through the ammeter A good ammeter has very low series resistance, so connecting it in series will not affect your circuit. Be careful when using an ammeter , because of its very low resistance , it can cause a short circuit if you use it by mistake to measure "voltage", so avoid connecting it in Parallel.

What does a ammeter do in a circuit?
An ammeter measured how many amperes of current are flowing in an electrical circuit.
What effect if any does connecting an ammeter in series with a resistor in a circuit have on the current through the resistor?
The Amp meter was design to allow current flow through the meter to measure with a minimal alteration to the original circuit. That is the ideal world, in reality the meter has some resistance and will lower the current flow. The multiple current setting on most meter will reduce the effects caused by the meter but you must be careful not to damage the meter by reading to high for the setting.

How is an ammeter converted to a voltmeter?
The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit. If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter. If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.
