Question

what is the height and the lowest total resistance that can be secured by combinations of 4 ohms 8 ohms 16 ohms and 20 ohms and what is the relationship between them of the resistors

Answer 1

Answer:

lowest=80/39

highest=48 ohms

Explanation:

lowest is when all are in parallel,

1/R=(1/R1+1/R2+1/R3+1/R4)

highest when all are in series

R=(R1+R2+R3+R3+R4)
