Calculate the resistance of a 270-cm length of copper wire with a 0.030-cm2 cross-sectional area. ( = 1.8 · 10-6 ohm-cm) r = ω 5.4 x 10-1 5.0 x 109 2.0 x 10-18 1.6 x 10-2

Given:-

The length of copper wire (L) = 270 cm

Area of cross-sectional (A) = 0.030

and specific resistance (ρ) = ohm-cm.

Use the formula  R=(Specific resistance*L)/A, to calculate the Resistance(R)

then, ohm

Simplify:

R = 0.0162 ohm = ohm

Therefore, the resistance of copper wire is,   Ω

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2
