Question

Why we take voltage on x axis not on y axis in a graph?

Answer 1

Voltage is usually taken on the y-axis whereas electric current is taken on the x-axis while finding the electrical resistance of a conductor of electricity...

Voltage is taken on the x axis whereas electric current is take in on the y-axis while finding the electrical conductance of a conductor of electricity...

Answer 2

Explanation:

I think you are talking about the AC current voltage

So it has been observed that AC current follows the sin graph that is the fluctuation of current after successive time intervals.

As

$i = i. \sin(wt)$

i. - max current

So

$v = i. \sin(wt ) \times resistance$

Therefore V. =i. *resistance

V. - max voltage

So

$v = v.sin(wt)$
