The resistance of the copper wire can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current. In this case, the voltage (V) of the battery is 4.5V and the current (I) in the wire is 0.90A. Plugging these values into the formula gives: R = 4.5V / 0.90A R = 5 ? Therefore, the resistance of the copper wire is 5 ?.
