What diameter must a copper wire have if its resistance is to be the same as that of an equal length of aluminum wire with diameter 3.48 mm ? d = ____________ mm please show steps and reasoning.
Part A What diameter must a copper wire have if its resistance is to be the same as that of an equal length of aluminum wire with diameter 1.64 mm ?
Residential building codes typically require the use of 12-gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as large as 20.0 A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire could rise to a high temperature and cause a fire. (a) Calculate the rate at which internal energy is produced in 1.15 m of 12-gauge copper wire carrying a current of 20.0 A. (b) Repeat the calculation...
A solenoid 10 cm in diameter and 630 cm long is made from copper wire of diameter 0.050 cm, with very thin insulation. The wire is wound onto a cardboard tube to make a solenoid. (a) Determine the resistance in the wire. You may take the resistivity of copper to be 1.68 times 10^-8 Ohm m. (b) The number of turns in the wire is ten. Find the current necessary to produce a magnetic field of strength 1.5T. (c) How...
A) A number 16 copper wire has a diameter of 1.291 mm. Calculate the resistance of a 34.0 m long piece of such wire. (Use 1.72×10-8 Ωm for the resistivity of copper.) B) 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 6.0 A for rubber insulated wire of that size. How much power would be dissipated in the wire of the above...
(a) How long must a 0.60 mm diameter aluminum wire be to have a0.54A current when connected to the terminals of a 1.5 V flashlight battery? m (b) What is the current if the wire is half this length? A
1. 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.) Use the formula for resistance remembering that the diameter is specified rather than the radius. 2. 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...
How long must a 0.70-mm-diameter aluminum wire be to have a 0.60 A current when connected to the terminals of a 1.5 V flashlight battery?
Copper and aluminum are being considered for a high-voltage transmission line that must carry a current of 49.2 A. The resistance per unit length is to be 0.172 Ω/km. The densities of copper and aluminum are 8960 and 2600 kg/m3, respectively. Compute (a) the magnitude J of the current density and (b) the mass per unit length λ for a copper cable and (c) J and (d) λ for an aluminum cable.
