Question

The graph between potential difference (on X-axis) and current (on Y-axis) for a conductor gives a straight line

• A. parallel to X-axis
• B. parallel to Y-axis
• C. passing through origin
• D. intercepting both X-axis and Y-axis

Answer 1

The Correct Option is C

Correct answer: passing through origin
 
Explanation:
According to Ohm's Law, the relationship between potential difference \( V \) and current \( I \) is given by:
\[ V = IR \] or equivalently, \[ I = \frac{V}{R} \] This equation represents a linear relationship between current and voltage. When potential difference (V) is plotted on the X-axis and current (I) on the Y-axis, the graph is a straight line passing through the origin, because when \( V = 0 \), \( I = 0 \). 

Hence, the correct answer is: passing through origin.
