Complete the equation that relates the
variables R, L, and A.
The resistance, R, of a wire varies directly
with it's length, L, and inversely with it's cross-
sectional area, A. The wire has a length of
500 cm, a cross-sectional area of 0.04 cm?,
and a resistance of 0.25 ohms.

The resistance, R, of a  wire varies directly with it's length,L and it's inversely propotional with it's cross sectional area A.

⇒ length,L = 500cm.

cross sectional area A = 0.04cm

resistance, R= 0.25ohms

Formula: [tex]\frac{RA}{L}[/tex] = K.

[tex]\frac{(0.25)(0.04)}{500}[/tex] = K

0.01 = 500K.
