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.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
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.
What is ammeter sensitivity?
Ammeter sensitivity can be determined by a change of scale for the ammeter which would introduce higher or lower resistance values depending on the reading required. A higher sensitivity for lower values of ampacity would require higher resistance in the measuring circuitry. Use Ohm's law to verify.
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 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.
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
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.
Which ammeter will have the biggest reading A series circuit powered by a battery consisting of an ammeter (ammeter 1) a lamp a second ammeter (ammeter 2) and another lamp.?
In a series circuit, the current is the same throughout all components. Therefore, both ammeter 1 and ammeter 2 will read the same current, as they are measuring the same flow of electrons in the circuit. The readings on both ammeters will be equal, so neither will have a bigger reading. The voltage drop across the lamps may differ, but that does not affect the ammeter readings.
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
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
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.
