How to calculate micro amps to amps?

1A=10^3 mA
1A=10^6
V=IR,
I=( 750/10^6),
=0.00075A THEN,
11K OHM= (11*1000),
= 11000 OHMS,
V=(11000*0.00075) =8.25V Ans.

I think everyone understands this

voltage drop refers to the voltage consumed by the particular resistance,

Here it is 8.25v and supply voltage whatever may be (here it is not mentioned) should be greater than 8.25v.

Right answer is 8.25 volt.

V = IR.
V = 750*10^-6*11*10^3.
V = 8.25V.

8.25 is the correct answer.

Micro amp is different from milli amp.
I = in Amp.

Amp -> millli Amp -> micro Amp,
1 --> 1000 --> 1000000.

So, I thought we should divide 750 microamps into 1000000 to get the unit Amp.

Please clarify.

V = IR
V = (0.750)*(11)
V = 8.25. (A).

Ans is [B] 82.5.

Given data: I = 750microAmps
= 750 * 10^-6 amps.

Resistance(R)= 11kohm= 11*10^3ohm
Voltage drop (Vd)= I*R.
= (750 *10^-6 )*(11*10^3),
= 82.5V.

i=750 microamps =>0.000750 amps.
r=11000ohms,
0.000750*11000 =>0.750 * 11=>8.25v.

Thanks all for explaining it.
