Question

A uniform wire is cut into three parts with their lengths in the ratio 2:3:6.
The ends of each of these three part are connected across an ideal battery
of 10 V. If a current of 5 A is drawn from the battery, find the initial
resistance of the wire​

Answer 1

Answer:

use the following formula-1/r1+1r2+1/r3

Answer 2

Explanation:

Step-by-step explanation:Length of piece 96cm

Sum of ratios 12

Third piece=(7/12)*96cm=7*8cm=56cm

Second pies=(3/12)*96cm=3*8cm=24cm

Third pies=(2/12)*96cm=2*8cm=16cm
