Question

what does the slope of I-V and V-I graph represent ?

Answer 1

From Ohm's law- V= IR
where, V = Voltage, I = current , R = Resistance
So, Slope of I-V graph = V/I = R
and the slope of V-I graph = I/V = 1/R = Conductance.

Answer 2

Answer:

The slopes of I-V and V-I graph are shown below.

For Graph 1:

Slope = y/x = V/I

According to Ohm’s Law, V = IR

Hence slope for 1st graph of I – V = V/I = R = Resistance

For Graph 2:

Slope = y/x = I / V

According to Ohm’s Law, I/V = 1 / R

Hence slope of 2nd graph of V – I = I / V = 1 / R = Conductance
