Question

what would be the values of v/i ratios when the potential difference is 0.8v 1.2v and 1.6v respectively ? what conclusion do you draw from these values​

Answer 1

Answer:

Given:V vs I graph.

To find the values of V:I ratio when potential difference is0.5V and 1V

Solution:

When potential difference is V=0.5V, then the corresponding value of I from will be I=0.2A

But by Ohm's law,

I

V

=R

Therefore,

I

V

=

0.2

0.5

=2.5Ω

When potential difference is V=1V, then the corresponding value of I from will be I=0.4A

But by Ohm's law,

I

V

=R

Therefore,

I

V

=

0.4

=2.5Ω
