# Question: Why cant we connect ammeter in parallel in circuit?

Contents

An ammeter has a very low internal resistance. So, if it is connected in parallel with a load, it will short-out that load in resulting a high current flowing through the ammeter may severely damage the ammeter (and possible harm the user), although most are fitted with fuses to protect them.

## Why should we not connect an ammeter in parallel and voltmeter in series?

A voltmeter has high resistance and if it is connected in series then it would consume all the current but an ammeter has low reistance and if it is connected in parallel then all the current would flow through ammeter and nothing would flow in the circuit .

## Why cant we connect voltmeter in series in circuit?

The voltmeter has a high resistance. When a high resistance voltmeter is connected in series it will not have any current to flow through the circuit. Therefore, a voltmeter connected in series acts more like a resistor and not as a voltmeter.

## Should an ammeter be connected in series or in parallel?

An ammeter measures the electric current in a circuit. In order for an ammeter to measure a devices current, it must be connected in series to that device. This is necessary because objects in series experience the same current.

## Can ammeter be used in parallel?

An ammeter is a device which measures the amount of current flowing in a circuit. It is a very low resistance(nearly zero) device. If it will be connected in parallel, it would draw most of the current and would get damaged. Hence, it is connected in parallel.

## Is galvanometer connected in series?

The galvanometer is converted into the ammeter by connecting the resistance in parallel with the circuit. And if the resistance is connected in series with a galvanometer, then it is used as a voltmeter .Comparison Chart.Basis for ComparisonGalvanometerAmmeterType of DeviceMechanicalMechanical or Electronic.8 more rows

## Why must a voltmeter have high resistance?

A voltmeter measures the difference in voltage between the two different points (say, on opposite sides of a resistor), but it does not adjust the amount of current passing between these two points through the device. It will therefore have very high resistance, so that it does not draw current through it.

## Why galvanometer is always connected in series?

Since galvanometer is a very sensitive instrument that it can not measure the heavy currents . to do so A shunt is connected with parallel with galvanometer to convert it into ammeter. Ammeter is always used in series in a circuit. so after that it can measure heavy currents in the circuit.

## Which is better galvanometer or ammeter?

But these two are having many dissimilarities. The main difference between these two is that the galvanometer shows both the direction and the magnitude of the current. But, the ammeter only shows the magnitude of the current .Difference between Ammeter and Galvanometer.ParameterAmmeterGalvanometerAccuracyIt is more accurate.It is less accurate.7 more rows
