A 4.00 A current runs through a 12-gauge copper wire (diameter 2.05 mm) and through a light bulb. Copper has 8.5×1028 free electrons per cubic meter. a)How many electrons pass through the light bulb each second? b)What is the current density in the wire? c)At what speed does a typical electron pass by any given point in the wire?
5. Number 12-gauge wire, commonly used in household wiring, is 2.053 mm in can mm in diameter and safely carry currents of up to 20.0 A. If a wire is carrying this maximu magnetic field strength produced by this wire at the following distances? ent, what is the m curr a) 0.30 mm from the wire's axis. (2) b) at the wire's surface (2) c) 0.75 mm beyond the wire's surface (2)
Household wiring often uses 2.0 mm diameter copper wires. The wires can get rather long as they snake through the walls from the fuse box to the farthest corners of your house. What is the potential difference across a 16 m long, 2.0 mm diameter copper wire carrying a 7.3 A current?
4a. The resistance of a 5.0 meter length of 14-gauge copper wire is 8.1 x 10 ohms/meter. How much energy loss occurs per second in the wire when a current of 20.0 amps is applied? Assume that the cross-sectional area is 2.1 mm', what is the shortest time in which the applied current could heat the wire by 15.0°C? You may assume that the density of copper is 8.92 x 10 kg/m and its molar heat capacity is 6.0 calories/mole/K....
The wires in a household lamp cord are typically 3.5 mm apart center to center and carry equal currents in opposite directions.If the cord carries current to a 100−W light bulb connected across a 120−V potential difference, what force per meter does each wire of the cord exert on the other? (Model the lamp cord as a very long straight wire.)
Chapter 27, Problem 012 The figure shows a resistor of resistance R = 6.05 12 connected to an ideal battery of emf 8 = 13.3 V by means of two copper wires. Each wire has length 23.2 cm and radius 4.20 mm. In dealing with such circuits in this chapter, we generally neglect the potential differences along the wires and the transfer of energy to thermal energy in them. Check the validity of this neglect for the circuit of the...
A number 12 copper wire has a diameter of 2.053 mm. Calculate the resistance of a 37.0 m long piece of such wire. (Use 1.72×10-8 Ωm for the resistivity of copper.) Tries 0/20 For safety, the National Electrical Code limits the allowable amount of current which such a wire may carry. When used in indoor wiring, the limit is 20.0 A for rubber insulated wire of that size. How much power would be dissipated in the wire of the above...
Household wiring often uses 2.0-mm-diameter copper wires. The wires can get rather long as they snake through the walls from the fuse box to the farthest corners of your house.
