An electrical circuit is connected up as shown above, which of the following is correct about the value of current flowing through the 1 ohm resistance?
R\(_T\) = \(\frac{(3 + 3) \times (3 + 3)}{(3 + 3) + (3 + 3)}\) + 1 = 4\(\Omega\)
V = IR, 12 = 4 x I, I = 3 A.
(The four 3 \(\Omega\) resistors will form two 6\(\Omega\)resistors in parallel, while the two 6\(\Omega\) resistors are in series with the one \(\Omega\) resistor.)
