Question
Which of the following relations is incorrect?
Options
R = `1/"k"("l"/"a")`
G = `"k"("a"/"l")`
G = `"k"("l"/"a")`
∧m = `"k"/"c"`
Solution
G = `bb("k"("l"/"a"))`
Explanation:
The inverse of resistance, R, is called conductance, G, and we have the relation:
G = `1/"R" = "A"/(ρ"l") = κ"A"/"l"`
