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-fourth of its original value. How many amperes of electrical current will flow through the wire? Choose the correct option
A) 2
B) 4
C) 8
D) 16
E) 24
Given that, I∝1/R, I*R is a constant value.   I1*R1 = I2*R2   I1*R1 = I2*R1/4   I2 = 4*I1 = 16 amperes   The answer is 16.
