What is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
What is the importance of ammeter?
An ammeter measures current, an important variable in electronics.
What is the 'job' of an ammeter in a circuit?
It measures the current.
What are the function of ammeter?
The purpose of an ammeter is to sense and display the magnitude of the current flowing through it. When connected in series with a branch of an electrical circuit, the meter displays the magnitude (and direction) of the current in that path ... which you can't otherwise tell just by looking at the circuit.
How is the reading on an ammeter be affected when one of the parallel resistors is removed?
decrease to half of its original value
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.
How voltage gets converted into current in an ammeter?
A: It must be be understood that current needs voltage other wise it is zero. An ammeter for DC is always a voltmeter that reads small IR drop to convert that reading into current present. Like an ohmmeter needs volts to read ohm. Both reading are volts it just convert those reading into whatever scale is switch to.
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.
How would you connect an ammeter if you want to measure the current coming through some device in a circuit?
HOW TO CONNECT AN AMMETER Always connect an ammeter in SERIES in a circuit. Always ensure that the ammeter has a higher reading range than the expected current load, including start-up spikes. An ammeter expected to read a steady current of 13A should have a max range of 20A.
What happens to the ammeter reading if resistor is removed?
Opening any circuit will stop the current from flowing.
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.
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 is the connection of the reading of a ammeter and the brightness of the bulb?
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.
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.
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.
What job does the ammeter do in the circuit?
The ammeter measures the amount of current in a circuit.
What will happen if you connect the ammeter in parallel with the component?
All the current would go through the ammeter. The whole purpose for making a measurement with an ammeter is to determine current draw through a component or circuit. If the ammeter takes all the current away from the device under test, the reading would be meaningless. Also, since the ammeter would present pretty much a dead short to the power supply, blown fuses or toasted components usually result.
