The electrical resistance in a conductor is given by:
Corresponding units:
ohm(Ω) = meter(m)/(siemens per metre (S/m) · square meter(m2))

The conductance is the reciprocal of resistance, thus:
G = 1/R = σ · S / l

Corresponding units:
siemens(S) = 1/ohm(Ω)

R: resistance
G: conductance
σ: conductivity
S: the cross-section area of the conductor
V: voltage
I: current
l: the length of the conductor © 2020 | Contact us | Terms of Use | Privacy Policy | Yellow Sparks Network
