Question

equivalent resistance​

Answer 1

a)to get 2 as equivalent resistance we must connect 1ohm resistor in series and connect 2ohm "resistors" in parallel and connect each other then u will get equivalent resistance as 2ohm.

b)connect all the resistors in parallel then the equivalent resistance will become 0.5ohm.

c)connect 2 ohm "resistors" in series and connect it with 1ohm resistor in parallel then the equivalent resistance will become 0.8ohm.

d)connect all the resistors in series then the equivalent resistance will be equal to 5ohm.

Hope u understood well
