A metal wire of resistance 2.30 10-8 is cut into two equal pieces that are then connected side by side to form a new wire the length of which is equal to one-half the original length. what is the resistance of this new wire?

Equal parallel resistors are governed by the formula


R = r^2/(2r) = r/2


r = 2.30 * 10^-8 ohms which is very tiny.


R = 2.30 *10^-8 / 2

R = 1.15 * 10^-8 ohms. <<<< Answer
