What is the equivalent resistance between A and B?
I tried to spot which resistors are connected in parallel and which in series but I just couldn't reform the combination into a solvable one.
So, I tried solving this using Kirchoff's current law:
Equation 1: I1 + I2 = I
Equation 2: I3 + I4 = I1
Equation 3: I2 + I3 = I5
Equation 4: I4 + I5 = I
Solving eq 1 and 2, we get Equation 5: I3 + I4 + I2 = I
Solving eq 3 and 4, we get Equation 6: I4 + I2 + I3 = I
This obviously gets me nowhere either so I'm stumped. The teacher simply said they are all connected in parallel so the equivalent resistance is R/5. But I don't see how.
