In the above attachment R₁ and R₂ are connected in parallel combination,
we know that,
The reciprocal of the combined resistance of a number of resistance connected in parallel is equal to the sum of the reciprocal of all the individual resistances. .i.e.,
1/R = 1/R₁ + 1/R₂
By substituting the values in the formula,
Now, R₁₂ and R₃ will be connected in series combination
We know that,
» The combined resistance of any number of resistance connected in series is equal to the sum of the individual resistances. i.e.,
R = R₁ + R₂
By substituting the values in the formula,
Now, R₁₂₃ and R₄ are connected in parallel combination so,
Now, R₁₂₃₄ and R₅ will be connected in series combination so,
Thus, the effective resistance between A and G is 16 ohms.
