How range of a ammeter is extended?

if we take resistance in parallel with ammeter then the range of ammeter will change.

What will happen if ammeter is put across a resistance in a circuit?

Maybe blow the fuse or burn out the wiring. An ammeter has an extremely low resistance. connecting it across the resistance causes the resulting parallel resistance to be slightly lower than the resistance of the ammeter 1/Rt = 1/R + 1/R(ammeter)

Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?

in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.

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

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.

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 happed if ammeter is placed in parallel with the component?

Ammeters have a very low resistance, as to not interfere with the circuit they are measuring current in. As such if you connect a very low resistance in parallel, the component is essentially shorted. A great many ammeter fuses have been blown because of this.

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.

Why in an ammeter low resistance is connected in parallel with the coil?

For protection.. Since the current prefer the short cut ..

How can you convert galvanometer into ammeter?

Since Galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.

What are the readings for the experiment - to convert a galvanometer int ammeter?

A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.

How does a series circuit work with an ammeter?

Actually ammeter is a galvanometer which is shunted by a resistance called shunt. For large currents major part of it is bypassed through the shunt. The parallel combination of shunt resistance and meter resistance is added to the circuit resistances , so the value indicated by the ammeter is slightly lesser than the actually value.
