Table 1 shows the typical resistivity values for various materials. Determine the resistance of wood, germanium, and gold samples which have an area of \( 2.0 \mathrm{~cm}^{2} \) and length of \( 3.5 \mathrm{~cm} \), respectively.
Expert Answer
As we know resistance R = ?×larea for wood, l = 3.5 cm A = 2 cm2 and ?= 1011 ??cm so Rwood = 1011×3.52 Rwood = 1.75×1011 ?
