If it is an ammeter designed for DC (direct current) like you have in a car and you connect it in an AC (alternating current) circuit (like you have in your home) it will read zero, even though it is obvious that current is flowing.

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 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 happened to the reading of ammeter and voltmeter if the number of dry cells are added in the circuit?

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!


How do you show forces in a diagram?

Forces can be shown in a diagram using arrows. The length and direction of the arrows represent the magnitude and direction of the force, respectively. You can label the arrows with the type of force and its value if known.


What are the properties that a device must have in order to measure temperature?

A device that measures temperature must have a temperature sensor that responds to changes in temperature, a way to convert the sensor's response into a numerical value, and a display or output to show the numerical temperature value. Additionally, the device should have the ability to calibrate and accurately measure a range of temperatures.

Why high resistances are not used in wheatstone bridge?

Because if high resistance is like kilo mega ohm is used , corresponding current through the balanced point is in the order of micro ampere, so you have to use micro ampere sensitive ammeter , otherwise normal ammeter always show zero reading
