Well, isn't that just a happy little question! When you add more dry cells to a circuit, the ammeter will show a higher reading because there is more current flowing through the circuit. The voltmeter reading will also increase because the total voltage of the circuit will be higher with the addition of more dry cells. Just remember to always paint with light and electricity in your circuits, my friend!

What happens to the ammeter reading if resistor is removed?

If the resistor is removed from the circuit, the total resistance in the circuit decreases. This causes the total current in the circuit to increase, which would result in an increase in the ammeter reading.


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.


What does the reading on a ammeter say when the switch is open?

An open switch in a circuit will stop all current flow so the ammeter should read zero amps.


What instrument measures current in an electric circuit?

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.


Describe the proper placement of a voltmeter in a circuit?

To measure voltage in a circuit, the voltmeter should be connected in parallel across the component or portion of the circuit where the voltage is to be measured. Ensure the voltmeter is set to the appropriate voltage range before making the connection. It is important to place the voltmeter correctly to obtain an accurate voltage reading without affecting the circuit's operation.

Will the rusting of nails in a sodium chloride - water solution effect the reading off a voltmeter or ammeter?

An ammeter or a voltmeter gives the reading of the flow of current, which is due to the movements of ions. When a rusted nail is immersed in the solution it will add the no of ions into the solution. This will increase the ion concentration and therefore will change the reading of a voltmeter and ammeter.


What would happen if a voltmeter were substituted for an ammeter?

Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.

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 an ammeter is connected in parallel?

It would be equivalent to adding a high value resistor (>10M ohms) in series in the circuit. Voltmeters typically present a high internal impedance so as to not change the current flow in the circuit you are tying to measure. the circuit wont work the voltmeter only takes a voltage reading power does not actually pass through the meter sometimes it can be used to measure very low leakage current using the hi impedance of the meter. EXAMPLE leakage offset from an amplifier. it could be into the nanoamps.

How is the strength of electric current measured with?

The strength of an electric current is measured in amperes (A) using an ammeter. An ammeter is a device that is connected in series in a circuit to measure the flow of current. The higher the current flowing through a circuit, the higher the amperage reading on the ammeter.
