(a)
Answer to Problem 21P
Explanation of Solution
Given:
The resistivity,
A rectangular solid made of carbon has sides of lengths:
Formula used:
It is known that resistance:
Where,
Calculation:
For x direction, current will flow from the right side to left side of the carbon rectangular. It means that the area (current path) is the right surface area
Since, the current passes through x-direction
By using the formula of resistance:
Put the given values in the equation
Conclusion:
The resistance for current that passes through the solid in the
(b)
