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.
Why should a millimeter have a low resistance?
An ammeter is placed in series with a circuit in order to measure the current. If it has any appreciable resistance, inserting the ammeter will increase the normal resistance of the circuit and reduce the value of the current flowing through it. The ammeter will, therefore, give an inaccurate reading (under-read). So the ammeter must have a very low resistance so that it has the minimum effect on the normal resistance of the circuit being tested. Ideally, the ammeter should have zero resistance but, of course, this is impossible.
What device shows the amount of energy a battery is producing?
That would have to be a 'wattmeter', but they're seldom available. In terms of more readily available instruments, you'd need to use a voltmeter, reading the battery's voltage, and an ammeter inserted in series in one of the battery's connections, reading the current from the battery. The rate at which the battery is supplying energy at any moment is then the product of the two meter readings.
The internal resistance of ammeter is?
The internal resistance of an ideal voltmeter is infinity ohms. The internal resistance of an ideal ammeter is zero ohms. Since there are no ideal voltmeters or ammeters, we consider the error introduced by adding these instruments to various circuits. In general, practical meters have high enough impedance (voltage) or low enough impedance (current) to not affect the reading more than the instruments accuracy specification, or to not affect the circuit more than is considered acceptable. There are times when this is not true, so we always consider the instrument and its contribution to systemic error.
What is a Dominant Reading?
A dominant reading also known as an invited reading, is the desired effect of the text such as an advertisement. It is the most 'obvious' reading of the text according to the dominant stereotypes.
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 will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
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.
What does it mean when the ammeter reading v?
v on a ammeterusually means Volts
What is a universal solvent and what can it not dissolve dissolve?
the universal solvent is water. and it can not dissolve most carbonates most oxides a few chlorides lead sulphate ,lead iodide, lead chloride barium sulphate, calcium sulphate most metals. I have not listed all of the insoluble materials here just a few. thanks for reading.
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.
How is an ammeter connected to reduce frequency errors?
Connecting an ammeter does not reduce the frequency errors.
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.
How is the ammeter reading when the magnet is pushed slowly into the coil?
You have to do the experiment you have been asked to do to find out.
How much current goes into the bulb if ammeter reading is 0.4?
The answer to this depends on where the ammeter is in the circuit. Assuming the ammeter is in series with the bulb and no other objects are attached, then the current is 0.4 Amps. Otherwise, your question is unanswerable without more information.
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.
