I = ?
V = 40V
R = 6.8 K Ohm
R = 6800 Ohm.
Since
I = V/R
I = 40/6800,
I = 0.00588,
I = 0.00588 (10^3)(10^-3)
I = 5.9 mA.
V = 40V
R = 6.8 K Ohm
R = 6800 Ohm.
Since
I = V/R
I = 40/6800,
I = 0.00588,
I = 0.00588 (10^3)(10^-3)
I = 5.9 mA.

V=IR, SO I = V/R.
THEN I = 40/6.8, I = 5.88-> Answer.
THEN I = 40/6.8, I = 5.88-> Answer.

1A = 1000 mA.
The result of the Ohm's Law is in A (ampere).
So 5.88 A = 5880 mA.
Am I doing wrong?

V = 40v.
R = 6.8 Kohms.
I = 40/6.8.
= 5.88mA.
R = 6.8 Kohms.
I = 40/6.8.
= 5.88mA.

I = V÷R.
I = 40÷6.8,
= 5.9Amp.
I = 40÷6.8,
= 5.9Amp.

Convert 40V to KV and calculate the current.
I = V/R. =40 * 10^3/6.8 *10^3= 5.88.
So, approximately 5.9 is the correct answer.
I = V/R. =40 * 10^3/6.8 *10^3= 5.88.
So, approximately 5.9 is the correct answer.

As we know ohms law v = ir.
We have to calculate i so i = v/r.
Substitute those values in the above formulae.
40v/6.8 * powerten(-3) = 5.88 it is near to 5.9.

I = V/R = 40 V/6.8 ohms = 5.88, or 5.9.
