How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
What happen if you change the position of ammeter in the circuit in parallel and series?
-- In a series circuit, no matter where you install the ammeter, it will always read the same current. -- In a parallel circuit, the ammeter may read a different current when it's moved to a different parallel branch.
Why wouldn't the shunt resistor in the ammeter protect the ammeter when the ammeter is connected in parallel?
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
The electrical meter that should be connected in series with a live circuit is?
ammeter
Why is it that a voltmeter is not connected parallel in a circuit?
An ammeter is connected in series with the circuit being measured because you want to measure the current flowing through the circuit, whereas a voltmeter is connected in parallel with the circuit being measured because you want to measure the voltage across the circuit. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of that law is that the current at every point is a series circuit is the same. The ammeter measures that current and, so long as its impedance is not too high, it won't disturb the circuit being measured. Kirchoff's voltage law, on the other hand, states that the signed sum of the voltage drops in a series circuit adds up to zero. A consequence of that law is that the voltage across parallel nodes must be equal. The voltmeter measures that voltage and, so long as it impedance is not too low, it won't disturb the circuit being measured. Formalities aside... An ammeter is a low impedance device. If you were to connect it in parallel with a circuit, it would draw all of the available current from that circuit. It and the circuit or its power supply would be damaged, because the ammeter represents a short circuit. A voltmeter is a high impedance device. If you were to connect it in series with a circuit, it would prevent any of the available current from reaching that circuit. While it and the circuit would probably not be damaged, the circuit would not function. Since practical meters are not perfect, the ammeter is not zero ohms impedance, nor is the voltmeter infinity ohms impedance. If you intend to measure both current and voltage in a circuit, it is normal protocol to measure the voltage across the circuit downstream of the ammeter, so that you would not be also measuring the additional voltage drop across the ammeter.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
Why should ammeter still be connected in a series despite the fact that the bulbs are already connected in parallel?
Because the ammeter connected in parallel will act as a short circuit.

Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
How would a ammeter be connected in a circuit?
An ammeter is always connected in series in the circuit.
What will a ammeter indicates if it is connected in parallel?
Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
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.
Why ammeter cannot be connected in parallel?
An ammeter has low resistance (ideally no resistance) because it is placed in series with other circuit elements to detect how much current is flowing. If it is placed in parallel with a component it will short-circuit it. That is a bad thing.
What happens when an ammeter is connected in parallel with a circuit?
SMOKE!!! Yiii-haaaa! An ammeter is always as low a resistance as possible. That way, the current that you measure in a circuit using the meter will be the same as if the meter were not there. So putting an ammeter in parallel with a circuit means that you just short circuited the circuit you were intending to measure. Poof! There goes your ammeter!An ammeter has a very low internal resistance. So, if it is connected in parallel with a load, it will short-out that load. The resulting high current flowing through the ammeter may severely damage the meter (and possible harm the user), although most are fitted with fuses to protect them.
How can an ammeter cause a short circuit?
An ammeter can cause a short circuit if it is connected in parallel instead of in series with the circuit being measured. This can create a low resistance path for the current to flow, bypassing the intended circuit and causing a short circuit.
Which part of the battery is an amp connected to in a car?
An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
