Question
What material is electrical resistance?
Open in App
Solution
A force that opposes the flow of current is electrical resistance.
It acts as a gauge for the difficulty of current flow in this way. Ohms
Ω
is a unit used to express resistance values.
Mathematically,
R
=
ρ
L
A
where
ρ
is
resistivity
,
L
is
length
,
A
is
cross
sectional
area
