Copper(II) sulfate generally has a higher ammeter reading than sodium chloride when dissolved in water. This is because copper(II) sulfate dissociates into more ions (Cu²⁺ and SO₄²⁻) compared to sodium chloride, which dissociates into only two ions (Na⁺ and Cl⁻). The greater number of ions in solution leads to increased conductivity and, consequently, a higher ammeter reading.

How do you measure the value of the amplitude of an electric current?
The value of the amplitude of an electric current is measured in amperes (A) using a tool called an ammeter. The ammeter is connected in series with the circuit to measure the flow of current. The reading on the ammeter displays the amplitude value of the 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.
Can ammeter be connected in neutral wire?
No, an ammeter should not be connected in the neutral wire of a circuit. It should be connected in series with the load on the live wire to measure current flowing through the circuit accurately. Disconnect the power source before connecting an ammeter and always follow safety guidelines when working with electrical circuits.
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.
The internal resistance of ammeter is?
The internal resistance of an ammeter is very low. This is necessary in order to minimize the impact of the ammeter on the circuit being measured, ensuring accurate readings of the current flowing through the circuit.
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 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 does it mean when the ammeter reading v?
v on a ammeterusually means Volts
What will the decrease of the light intensity on an LDR do to the ammeter reading?
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
How do you measure the value of the amplitude of an electric current?
The value of the amplitude of an electric current is measured in amperes (A) using a tool called an ammeter. The ammeter is connected in series with the circuit to measure the flow of current. The reading on the ammeter displays the amplitude value of the current.
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.
