Question

From the observation of Ohm's law I $\to$ V graph is drawn here.
From that which points are concluded?
P: I $\to$ V graph is a straight line.
Q: Ratio of V and I remains constant every time.
R: The electric current in a conductor increases in same proportion with the increase in voltage.

• A. Statements P, Q and R are all true
• B. Statements Q and R are true
• C. Statements P and R are true
• D. Statements P and Q are true

Answer 1

The correct option is A Statements P, Q and R are all true

Given is the graph of V vs I.

From this we can conclude that it is straight line.

Ratio of V and I is resistance and it remains constant for particular material.

And if V = IR so if Resistance is cosntant for particular conductor then current increases with increase in voltage.
