answer the 16th question​

Answer 1

Answer:

Heya mate here's your answer:-

The given condition forms x greater than y greater than z.

Resistance of AB is x,across CD is y and across EF is z as given in the figure in the given rectangular cross section (a×2a×4a).

• Resistance= pL/A

where p=resistivity

• L=length of the conductor
• A=area of cross section

For resistance between A and B

• L=4a
• A=2a*4a
• x=p a/(2a×4a)=p/8a=(1/8)(p/a)

For resistance between E and F

• L=4a
• A=a*4a
• z=p a/(a×4a)=p/2a=(1/2)(p/a)

Hence, option 2.) x greater than y greater than z
