is,1 A =………... milliampere=……..A microampere=……………….An instrument

called…….. measures electric current in a circuit. It is always connected in…………. in

a circuit through which the current is to be measured​

Answer 1

Answer:

The SI unit of electric charge is Coulomb which is represented as C,which is equivalent to charge contained in nearly 1.6 × 10^(18) electrons.

The electric current is expressed by a unit called Ampere represented as A.

One ampere is constituted by the flow of 1 coulomb of charge per second, that is 1 A = 1 C / 1 s.

Milliampere = 1 mA = 10^(-3) A.

Microampere = 1 uA = 10^(-6) A.

An instrument called Ammeter measures electric current in a circuit. It is always connected in series in a circuit through which the current is to be measured.

Charge:- It is the basic property of a substance.

Current:- It is the rate of flow of charge in a circuit.

Circuit:- It is the connection between all the instruments with the help of wires through which the current passes.
