Explanation:
where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
when the voltage is 5 volts and the power is 2 watts. The resistance R is equal to square of 5 volts divided by 2 watts, which is equal to 12.5 ohms.

Answer:
I = 0.4 A
Explanation:
V = IR ( ohms law)
Hence, 2 = 5I
I = 2/5
I = 0.4 A
