Question

We have four resistors A, B, C and D of resistance 4ohm, 8ohm, 12 ohm and 24 ohm respectively. What is the Lowest and highest resistance which can be obtained by combining these four resistors? i will mark brainliest

Answer 1

it is very easy

for highest resistance connect all resistors togather in a same wire, i mean connect all of them in series where total resistance would be 48 ohm

for minimum resistance connect all of them in parallel connection so it will form the least resistance. the total resistance would be 2 ohm


concluding 

highest resistance is A+B+C+D in series

least resistance in parallel
1/4+1/8+1/12+1/24=5/10
so least resistance is 2 ohm

Answer 2

See the image and ask if there is any problem. I know writing is bad.
