Surely you mean,
“Calculate the voltage across a 500 ohm resistor with 1.4 amps flowing through it”.
An “Ohm” is the unit of resistance. The question would not be asking you to calculate something they explicitly tell you the value of.
The resistance of the resistor is 500 Ohms and it has a current of 1.4 amps flowing through it.
The voltage drop across the resistance is equal to (using Ohm’s Law to figure this out),
V = RI
Where R is the resistance and I is the current through the resistor.
Plugging in the values we know for R and I,
V = (500 Ohms) * (1.4 Amps)
V = 700 volts
There must be a 700 volt potential difference applied across the resistor in order to cause 1.4 Amps to flow through it.

V=RI
if ur in high school physics, u need to get help cuz this is really simple

u need calculate what?
may be voltage
V = I * R
POWER = V * I * COS Ó¨
P = I² * R
