The term 'burden' is used to describe the secondary load applied to an instrument transformer; the reason for this is so that it is not confused with the 'load' supplied by the high-voltage circuit to which the transformer's primary is connected. A burden is either a measuring instruments (ammeter,voltmeter, wattmeter, etc.) or protective relay, depending on the function of the instrument transformer. 'V.A' is the symbol for 'volt ampere', which defines the 'power' rating of the instrument transformer.
a dc ammeter is a ammeter which has three pins and it works by two wires.
An ammeter measures amperage not voltage.
An ammeter measures current, an important variable in electronics.
To increase the range of an ammeter, you connect a very low impedance resistor in parallel with the ammeter.
Yes, as long as the burden of these ammeters does not exceed the VA rating of the CT.

The disadvantage of using a voltmeter and ammeter on circuit measurements is that internal burden in both these instruments can affect circuit operation so much as to make a measurement useless.
if we take resistance in parallel with ammeter then the range of ammeter will change.
An Ammeter and a brick is a brick.
ammeter real picture
a dc ammeter is a ammeter which has three pins and it works by two wires.
How do you connect an ammeter to a circuit?
an ideal ammeter will have zero resistance
connect ammeter in series with load.
Ammeter
dc ammeter has three connecting pins while ac has four
