Question

five resistance of 20 ohms , each are connected in parallel. four such combinations are connected in series. what is the total resistance.​

Answer 1

Answer:

R=4ohm

Explanation:

Resultant resistance of a parallel combination of four 16 ohm resistance is

1/R=1/16+1/16+1/16+1/16=4/16

R=4 ohm

so total resistance =4+4+4+4=16ohm
