3. In household wiring, usually l2-gauge copper wire {diameter 2.05 mm] is used. A light bulb is connected to power supply through such a wire. A 1.5-An1pere current runs through the wire and the light bulb. a. What is the resistance of I'D-meter length of the wire?r b. How many electrons pass through the light bulb each second? c. 'What is the current density in the wire? d. If we were to use wire of twice the diameter, which of the above answers would change?r Would they increase or decrease? You do not need to do any calculations
