The correct answer to this question is A, 1 ohm. This question is related to Ohm's Law. It is one of the most important laws regarding electrical circuits. The law states that a current passing through a conductor will be proportional to the voltage over any resistance that occurs.
A simple formula is used to describe Ohm's law. It is I = V/R. Each letter in the formula represents something. The I represents the current, which is in amps, V is the voltage in volts, and the R is the resistance in ohms. The formula can also be written as V = IR or R =V/i.
