Homework Equations
The Attempt at a Solution
(a)I think there are two pairs of resistances are in parallel,one pair is the 40ohm and 50ohm resistances,and the other pair is the 30ohm and 60ohm resistances.But I'm not to sure
So the Req I've calculate is 152.2ohm...
but I have no idea in how to calculate the Req in (b)...
Thanks
