Solve this:
Q 10 State the change in the ammeter reading observed when a
resistance wire in a circuit is replaced by a wire of same
matertial and same length but comparatively double cross - section
area, keeping the source of potential difference the same

Sakshi Kanwar · Accepted Answer

Dear Student
If the wire has same length and is of same material and double the
crossection than the resistance becomes half As we know I=V/R and V
is same so current reading in ammeter will be double of the
previous
