Question

Four resistances of 40 ohms each are connected in parallel. Four such combinations are connected in series. What is the total resistance ?

Answer 1

Answer:

i hope it will help you

Step-by-step 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=4ohm

Four such combinations are connected in series ,

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