What will happen to an ammeter reading if the resistors are connected in parallel?

You would be drawing more current. It would be the same as adding more load to the circuit in a vehicle, say more lights. The lights would just be seen as more load (a resistive load in the case of incandescent lights). Add more lights (resistors) and more current is needed. The ammeter would indicate a higher current draw.

How is the reading on an ammeter be affected when one of the parallel resistors is removed?
decrease to half of its original value
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
How do you calculate the ammeter reading?
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
How do you use an ammeter?
The Positive side of the Ammeter should be connected to the positive side of the battery and the Negative side should be connected to the Globe/Conductor/Insulator to provide a valid reading.
What happens when an ammeter is connected wrong?
Ammeters have a low impedance, so if they are incorrectly connected in parallel to your load instead of in series, more current will flow through the circuit and the ammeter will almost act like a short. There is potential to burn our the ammeter.
A 9 V battery is hooked in series with two resistors R1 75 and R2 100?
You'll get a reading on the ammeter showing 15 mA
How is an ammeter connected to reduce frequency errors?
Connecting an ammeter does not reduce the frequency errors.
What happens to the ammeter reading when a lamp is added to a circuit which contains two cells and a lamp in series?
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
Can ammeter be connected in neutral wire?
No, your live (brown) cable takes the load and pulls the amps from the supply, not the neutral. Your ammeter should be clipped on the live to get a correct reading.
How do you connect more than one ammeter to a circuit?
Two ways to connect an ammeter, You can use a direct reading type, by connecting the ammeter in series with the load. You can use a current transformer type or CT. The current transformer looks like a wire wrapped donut with two terminals on its side with a hole through the middle. you pass the wire carrying the load through the center. Connect the direct reading meter to the two terminals. A CT type meter allows you to measure higher currents.
As you add more lamps to a parallel circuit what will the ammeter reading do?
If the amp meter is in series ahead of the first parallel branch of lamps the meter will read an increase in current.
