Consider a rectangular block of metal of height A, width B and length C as shown in the
figure. The block is connected to power of voltage V in two cases: in (a) case the current
through the block is IAB. Find the current in (b) case via IAB, A, B and C values.

I = I * (C/A)^2
Объяснение:
You need to show the picture, despite it being a physics home assignment.
Main formula:
I = U/R and R = p * L/S
For the first case:
I = U / (p * C/AB) find U: U = I
* (p* C/AB)
For the second case:
I = U/(p * A/BC) put U:
I = I * (p* C/AB) / (p * A/BC)
I = I * (C/A)^2
Good luck with the midterm exams.
