Question

a wire of uniform cross section and having resistance 160 ohm is is cut into 4 equal parts and joined parallel with each other if this combination is connected to a battery of 10 volt calculate the total current drawn from the battery​

Answer 1

Answer:

1 A

Explanation:

V/R=I

by dividing into 4 parts, R of each part is 40 as resistance is directly proportional to Length.

Then by using parallel combination formula we equivalant resistance as 10

I = 10V/ 10 Omega
