Question

calculate the equivalent resistance...
(best answer will be marked brainliest)​

Answer 1

Answer:

resistance-is offered by a cube of material of side ones 1 metre when current flows perpendicular to its opposite faces

it's resistance =57ohm

Answer 2

Explanation:

Since the end points of the 20,20,10 ohms are same, all three of them are in parallel...so equivalent resistance is 5 ohms

now 5 and 6 ohms are in series....so net resistance is 11 ohm

for R in parallel Req=1/R1+1/R2+1/R3.....

For R in series Req=R1+R2+R3......
