2 milliamperes = 2 * 10^-3 A.
= 2 * 10^3 * 10^-3/10^3 A.
= 2 * 10^3 * 10^-3-3 A.
= 2 * 10^3 * 10^-6 A.
= 2000 µA.

1 microamp = 10^-6 amp.
1 amp = 10^6 microamp.

So,
2 milliamp = 2*10^-3 amp.
= 2*10^-3*10^6 microamp.
= 2000 microamp.

1milliA = 10^-3.
2milliA = 2*10^-3 = 0.002A,
1μA =10^-6A = 0.000001A,
So that 1A = 1000000μA,
= 0.002A * 1000000μA,
= 2000μA.

1 mA = 1*10^-3 ampere.

1 micro amperes = 1*10^-6 ampere.

= 2*10^-3/10^- 6.
= 2*10^(-3+6).
= 2*10^3.
= 2*1000 = 2000.

Answer D.

1milliamperes = 1000 microamperes. Therefore 2 milliamperes = x.

Cross multiple we get x = 1000 * 2.

Therefore x = 2000.

1milliamperes = 1000 microamperes. Therefore 2 milliamperes = x.

Cross multiple we get x = 1000*2.

Therefore x = 2000.

@Minikandan make wrong calculation. In a equation if one thing multiply then on other side it will divide.

A = 10^-6 in 2*10^-3.

A = 2*10^-3-6.

A = 2*10^-9.

A = 2000*10^-6.

So it is answer D.

= (2 * 10^-3)/10^-6,

= 2000 * 10^-6 A,

Milli = 10^-3, and Micro = 10^-6.

x = 10^-6 ampere in 2 * 10^-3.
x = 2 * 10^- 9.
x = 2000*10^- 6.

x = 2000 microampere.
