Question
Find the effective resistance in the following circuit diagrams (Fig.):
Solution
In the given network, between B and C the series combination
of two 6 Ω resistors is connected in parallel with the third 6Ω resistor.
`1/"R"_"equivalent" = 1/(6 +6) + 1/6 = 1/12 + 1/6 = 3/12 = 1/4`
`"R"_"equivalent" = 4 Omega`
Now, between P and Q, two 6 Ω resistors and 4Ω resistor are connected in series.
:. total resistance between P and Q is:
`"R"_"total"` = 6 + 6 + 4 = 16Ω
