Compared to the current in the 10.-ohm resistance in the circuit shown at the right, the current in the 5.0-ohm resistance is
a. one-half as great
b. one-fourth as great
c. the same
d. twice as great

The answer is d. Twice as great.

Explanation:

The German physicist and mathematician Georg Simon Ohm says in his basic law of electrical circuits or Ohm's law that the potential difference V that is applied at the ends of a conductor is proportional to the intensity I of the current that circulates and that the electrical resistance R is the ratio factor between I and V.

The equation would be I = V / R

If by any chance R is reduced because it is inversely proportional, the current would increase.

So if the current goes from 10 to half 5, its current would double.
