Compute the voltage drop along a 24-m length of household no. 14 copper wire (used in 15-A circuits). The wire has diameter 1.628 mm and carries a 13-A current. The resistivity of copper is 1.68×10−8Ω⋅m.
Compute the voltage drop along a 22 m length of household no. 14 copper wire (used in 15-A circuits). The wire has diameter 1.628 mm and carries a 14 A current. Express your answer using two significant figures.
please answer both parts of this question (a & b). will upvote as long as I can read through the assistance, thanks in advance (a) Compute the voltage drop along a 20m length of copper wire that carries 12A current. The wire has diameter 1.628 mm. Resistivity of copper is p = 1.7 x 10-89m.s Hint: Use Ohm's law and the formula of resistance in terms of the resistivity. b) Two copper wires have the same resistance. If one has...
An aluminum bar 3.68 m long has a rectangular cross section 1.01 cm by 5.17 cm . a. What is it's resistance? (I got 1.987x10^-4 but the program says this is wrong) b. What is the length of a copper wire 1.50 mm in diameter having the same resistance? (I got 0.02041 but it also was wrong) A 14.0 gauge copper wire of diameter 1.628 mm carries a current of 11.0 mA. What is the potential difference across a 2.25...
How much is the resistance of 50 ft if household 14 gauge Cu wire (1.63 mm in diameter)? Resistivity of Cu is 1.70 *10^-8 Ohm m, if the current 15 A is flowing in this wire, then how much is the voltage drop on it?
A current of 10A passes through the electric wire and there is a voltage drop of 8V along the wire. The diameter of the wire is 3mm and the length is 12m. The wire is wrapped with a 1.5-mm-thick cover whose thermal conductivity is k = 0.15 W/m·°C. If the insulated wire is exposed to calm atmospheric air at ?∞ =30°C, determine the temperature at the interface of the wire and the plastic cover.
A copper wire 10 m long must experience a voltage drop of less than 1.0 V when a current of 3.0 A passes through it. Using the data in Table 12.1, compute the minimum diameter of the wire.

Consider a straight piece of copper wire of length 8 m and diameter 8 mm that carries a current I = 4.5 A. There is a magnetic field of magnitude B directed perpendicular to the wire, and the magnetic force on the wire is just strong enough to “levitate” the wire (i.e., the magnetic force on the wire is equal to its weight). Find B. Hint: The density of copper is 9000 kg/m3 .
