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 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.
Zero error of a spring balance?
zerro error in a spring balance affects the accuracy in the weight. To find zero error in spring balance, you have to first find the least count of the spring balance and then suspend it freely, if the outcome is +1, the zero error is +1 and if it is -1 ,the zero error is -1.
What is a zero error?
if the zero line of vernier scale is not conciding with main scale the zero error exists.Knowing the zero error necessary correction can be made to find correct measurement..Such a correction is called zero correction
Can 47mm be azero error in screw gauge?
No, a zero error in a screw gauge indicates that the initial reading is not starting from zero. So, 47mm cannot be a zero error unless the screw gauge is not calibrated correctly.
What is resistance of an ideal ammeter?
ideal ammeter has zero internal 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 is an ideal ammeter?
An ideal ammeter is a device that measures electric current and has zero resistance, producing no voltage drop when connected in a circuit. This ensures that the current being measured is not affected by the presence of the ammeter itself, providing an accurate reading of the current flowing through the circuit.
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.
Why the resistance of an ammeter is bery low?
0. An ammeter is placed in series with the circuit in question; if its' internal resistance is high, it will change the current flow, thus making the measurement meaningless. For the same reason an ideal voltage meter will have infinite resistance.
How do you find the zero error and zero correction in sgrew gauge?
we can find the zero error by closing the jaw of screw guage if the zero of main scale(MS) is concide with the zero of circular scale (CS) there is no zero error and if they are not concide there is a zero error in screw guage .
Define the term zero error of vernier calliper?
The zero error of vernier calliper is defined as :-The zero error is equal to the distance between the zero of the main scale and the zero of the vernier scale.
What is Positive zero error?
if the zero of vernier scale lies on the right side of the zero of the main scale , then error is known as a positive error .
If ammeter 1 reads 2.A what will ammeter 2 read?
If an ammeter read 2A, another ammeter would probably also read 2A. Keep in mind that every measurement involves error, and the equipment has a stated accuracy. If, for instance, the ammeter used had a 1% tolerance, than 2A actually means anywhere between 1.98A and 2.02A.
What is the function of mirror in ammeter?
That's great I have learned something new
How can you calculate zero error and zero correction?
Zero error occurs when a measuring instrument does not read zero when the true value is zero. To calculate zero error, you take a measurement of a standard reference (ideally zero) and note the difference between this reading and the expected value of zero. Zero correction is then determined by subtracting the zero error from your subsequent measurements to adjust them to the true value. For example, if the zero error is +2 units, you would subtract 2 from all future readings to correct them.
When voltage is zero why ammeter shows current?
Because you are testing on the ground side of the circuit in question.
