Question

how can three resistors of resistance 2 ohm, 3ohm and 6 ohm can be connected to give total resistance of 4 ohm and 9 ohm​

Answer 1

Answer:

for 4 ohm resistance

                  ---(3ohm)---

---------------                      --------(2ohm)--------

                  ---(6ohm)---

hope u understand the diagram

for 9 ohm resistance

we can't
