question 38

Multiple Choice

A potential difference of V = 0.500 V is applied across the length of a rectangular block of silicon (Si) with resistivity 8.70 *10^-4 $\varOmega$ m.The dimensions of the Si block are: width 1.50 mm;thickness 0.400 mm;and length L = 20.0 cm.You may assume that the current density in the Si block is uniform and that currents in Si obey Ohm's law.What is the resistance of this Si block?

• A)92.3 \(\varOmega\)
• B)362 \(\varOmega\)
• C)78.4 \(\varOmega\)
• D)290 \(\varOmega\)
• E)452 \(\varOmega\)
