In Ohm's law, I equals E divided by which quantity?

Explanation:
Current is voltage divided by resistance. Ohm's law, V = IR, shows that for a given voltage, the current is reduced when resistance goes up. Rearranging gives I = V/R, so the quantity in the denominator is resistance. The other options don’t fit this direct relation: power isn’t the divisor in this basic form, dividing by voltage doesn’t yield the general current expression, and dividing by current wouldn’t produce a valid, useful form of Ohm’s law.
