The amount of electrical current that flows through a wire is inversely proportional to the resistance in that wire. A wire originally carries 4 amperes of electrical current. Then the resistance is reduced to one-half of its original value. How many amperes of electrical current will flow through the wire? Choose the correct choice from the following options
A) 1 B) 2 C) 4 D) 8 E) 12
Given that, I∝1/R, I*R is a constant value.   I1*R1 = I2*R2   I1*R1 = I2*R1/2   I2 = 2*I1 = 8 amperes   The answer is 8.
