Question

The slope of current $\left(I\right)$ versus voltage $\left(V\right)$ graph is called :

• A. Resistance
• B. Resistivity
• C. Specific conductance
• D. Conductance

Answer 1

The correct option is D Conductance

Answer is D.
In a pure resistance the relationship between voltage and current is linear and constant at a constant temperature, such that the current ( i ) is proportional to the potential difference V times the constant of proportionality 1/R giving i = (1/R) x V.
Here, the slope 1/R is nothing but the conductance.
Conductance is inversely related to resistance. If R is the resistance of a component or device (in ohms), then the conductance G (in siemens) is given by: G = 1/R.
