When a current of intensity (1) passes
through a conductor of length (L) and
area of cross-section (A) and when
using the same battery and changing
the conductor used from the same
material, we find that the current
has become (31) and therefore the
dimensions of the new conductor are

• length 2L and area 6A
  
• length 3L and area 3A
  
• Length 18L and area 2A
  
• length=1/3L and area 1/3A
