Solution

Q.
The values of mA and $µ A$ are:

1 $10^{- 6} a n d 10^{- 9} A r e s p e c t i v e l y$

2 $10^{- 3} a n d 10^{- 6} A r e s p e c t i v e l y$

3 $10^{- 3} a n d 10^{- 9} A r e s p e c t i v e l y$

4 $10^{- 6} a n d 10^{- 3} A r e s p e c t i v e l y$

Ans.
(2)

An ampere is the SI unit of electric current.

$1 A = 1000 m A o r 1 m A = \frac{1}{1000} A = 10^{- 3} A T h u s, 1 μ A = 10^{- 3} \times 10^{- 3} A = 10^{- 6} A$

Solution

Q. The values of mA and µA are:

1 10-6 and 10-9 A respectively

2 10-3 and 10-6 A respectively

3 10-3 and 10-9 A respectively

4 10-6 and 10-3 A respectively

Ans. (2) An ampere is the SI unit of electric current. 1 A = 1000 mA or 1 mA =11000 A=10-3 AThus, 1μA=10-3×10-3 A=10-6 A
