The current supplied to an air conditioner unit is 4.00 A. The air conditioner is wired using a 10-gauge (diameter 2.588 mm) wire. The charge density in the wire is electron/m3.
Find the magnitude of current density in the air conditioner’s wiring.
Find the magnitude of the drift velocity in the air conditioner’s wiring.
A wire has a circular cross-section with a radius mm. The current density in the wire is non-uniform and is modeled as , where is a constant with units of . The magnitude of is . What magnitude of current is carried by the inner section of the wire from the axis to ?
A cylindrical wire with radius has a current density , where . What is the current through the wire?
