What is the formula that relates conductance and resistance?

The correct relationship between conductance and resistance is established by the formula where conductance is equal to the reciprocal of resistance. This means that conductance quantifies how easily electricity can flow through a material, while resistance measures how much that flow is impeded.

In mathematical terms, if you denote resistance as "R," then the conductance "G" can be expressed as:

G = 1 / R.

This relationship highlights that as resistance increases, conductance decreases, indicating that materials with high resistance are poor conductors of electric current. On the other hand, materials with low resistance have high conductance, allowing for efficient current flow.

Understanding this relationship is crucial in electrical engineering and electronic security systems, as it helps technicians design and evaluate circuits effectively.
