How much current flows through a resistor of 285 ohms if the potential difference across the resistor is 122 volts?

The choices can be found elsewhere and as follows:

a. 2.34A 
b.4.28 x 10 ^-1A 
c. 4.28 x 10A 
d.2.34 x 10^-1A 

You can answer this using the equation I = V / R

I = V / R 
I = 122 / 285 = 0.428A = 4.28 * 10^-1 A 

Hope this answers the question. Have a nice day.
