A wire is made of a material with a resistivity of 6.56847 × 10−8 Ω · m. It has length 4.63161 m and diameter 0.76384 mm. What is the resistance of the wire? Answer in units of Ω.
Homework Answers
Here,
resistivity, p = 6.56 *10^-8 Ohm.m
for the resistance
Resistance = p * length/area
Resistance = 6.56 *10^-8 * 4.63161/(pi *(0.76384/2 *10^-3)^2)
Resistance = 0.663042 Ohm
the resistance of the wire is 0.663042 Ω
