Question

Can anyone help me with this Physics Question?
Answer is 1 ohm.
I just need the solution.

Answer 1

Resistances QR and SR are in series:

Equivalent Resistance of QR and SR = 1+1 = 2Ohms.

Now Resistances QR and QS are in Parallel:

Equivalent Resistance of QR and QS=
$(\frac{1}{2} + \frac{1}{2} )^{ - 1}$
= 1 Ohm.


Now Resistances PQ and QR are in series:
Equivalent resistance of PQ and QR = 1+1=2Ohms.


Now the resistances QR and PS are in parallel:

${( \frac{1}{2} + \frac{1}{2} )}^{ - 1} = 1$
Thus the Equivalent Resistance between A and B is 1 Ohm.

Answer 2

Hay mate,
Her answer is right
Because I know the answer
And I think that, if I give you full explanation it is only waste of time did you understand
OK
HAVE A NICE DAY
