Question

given are three resistence of 3 ohms each. how can they give a total of 9,1 and 2.0 ohm? draw a suitable diagram for each case

Answer 1

1.when resistances are connected in series = 3+3+3=9 ohm

2.when they are connected in parallel=1/3 + 1/3 +1 3

3/3= 1 ohm

3.when 2 resistance are connected in series and 1 parallel to it

so 1/6 + 1/3

=3/6

= 2 ohm
