The potential differnece across a resistor is 4.4 * 10^2 V. If the resistance of the resistor is 1.8 k ohms, how much current flows throught the resistor?
R=1.8 k ohms
I=?
4.4*10^2 V
V=IR
I=V/R
= 4.4 * 10^2
___________ = 2.44*10
1.8 * 10^
24.4 A
is this done correctly?

Of course not.
440 volts divided by 1800 ohm is not 24 amps. 
is it .24 amps?

yes, or 240mA

which answre would be apropriat for this question
240mA
or .24 amps 
MC, either is correct. The most common usage is probably 240mA, but it is no more correct than .24 A

ok, thanks
