Question

answer this anyone plz!​

Answer 1

Answer:

1V

Explanation:

As we know, V=IR ,

I=V/R

I=6/100 Amp.......(1)

Let R' be the resistance of 50cm wire:

3m->100ohm

300cm->100 ohm

50 cm-> (100/300)*50

R'= (50/3) ohm -----(2)

Current in wire will remain constant, So

V=IR'

from (1)&(2),

V=(6/100)×(50/3)= 1V

Answer 2

Answer:

1V

I =V/R = 6/100 =0.06A

Resistance is directly proportional to length for constant cross section.

Resistance of 50cm length wire = 100 * 0.5/ 3

Voltage across 50cm length = IR = 0.06 * 100*0.5/3 1V
