This answer is not 32 µA. It's 320 ma
= 3.2*10^-5,
= 3.2*10^-5*10^-3,
= 3.2*10^-2,
= 320mA.

1A = 10^6micro amp.
1micro amp = 10^-6A.
3.2*10^-5A = 32/10*(10^-5)A,
= 32*(10^-1)(10^-5)A,
= 32*10^-6A,
= 32micro amp.

For getting micro A, it should be 10^-6,
So, to get 10^-6 we have to divide it by 10 i.e multiply by 10^-1.
So, if we divide by 10, to make the value the same we have to multiply by 10.
i.e 3.2 x 10^-5 x 10^ -1 x 10)= 32 x 10^-6 = 32 micro A.

1 micro−ampere = 10 − 6 A = 1/10^6. = 0.000001
3.2 × 10–5 A = 3.2 x 1/10^5 = 0.000032.
Therefore; 3.2 x 10^-5 A= 32 micro- ampere.

= 3.2*10^-5
= 3.2*10/100000
= 32/100000.
= 32 MA.

3.2(1/100000) then solve this and get 32mA.
