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?

  • physics - ,

    Of course not.

    440 volts divided by 1800 ohm is not 24 amps.

  • physics - ,

    is it .24 amps?

  • physics - ,

    yes, or 240mA

  • physics - ,

    which answre would be apropriat for this question
    240mA
    or .24 amps

  • physics - ,

    MC, either is correct. The most common usage is probably 240mA, but it is no more correct than .24 A

  • physics - ,

    ok, thanks
