As we have to find current so I = V/R.
So I = 30/3.3000000.
I = 0.0000090909,
I= (0.0000090909 * 10^+6 ) * (10^-6).
I= 9.09 uA.
So I = 30/3.3000000.
I = 0.0000090909,
I= (0.0000090909 * 10^+6 ) * (10^-6).
I= 9.09 uA.

V = IR.
v = 30v.
r = 3.3 M ohms.
I = ?
Solve,
I = V/R
I = 30/3.3 M ohms
I= 9 Micro Amperes.
v = 30v.
r = 3.3 M ohms.
I = ?
Solve,
I = V/R
I = 30/3.3 M ohms
I= 9 Micro Amperes.

Clarification;
1 Ohm = 10^6 Megohms.
1 Ohm = 10^-6 micro ohms.
*Note: This is like proportion for converting from Mega to micro.
*10^6 Mega ohms = 10^-6 micro ohms.
* So multiply both side with 1/6 then the see the result.
Always remember this formula: P = IV = I^2*R = V^2/R.
Then I = V/R.
I = 30/3.3 micro ohms.
I = 9.090909 micro ohms.
So answer is A.
1 Ohm = 10^6 Megohms.
1 Ohm = 10^-6 micro ohms.

As we have to find current so I = V/R.
So I = 30/3.3000000.
I = 9uA.
So I = 30/3.3000000.
I = 9uA.

I=V/R,
SO, I=30/3. 3000000.
I=9. 09*10^6.
I=9 µA.

1Kohm=10^3 ohms
1Mohm=10^6 ohms
1 M ohm=1000 ohms
so,formula for I=V/R
I=30/3.3M ohms
I=9000M ohms
I=9milli ohms
1Mohm=10^6 ohms
1 M ohm=1000 ohms
so,formula for I=V/R
I=30/3.3M ohms
I=9000M ohms
I=9milli ohms
