A graph of I versus V for a fixed resistor is:
|
A straight horizontal line
|
|
A curved line
|
|
A straight diagonal line
|
|
Only diagonal in the positive direction
|
Explanation:
Detailed explanation-1: -According to owm’s law current I∝V=R1V. where R1 is the constant of proportionality which is called conductance. we can see from the graph that I∝V so slope will be conductance or Resistance is IV and thence the slope of given graph is the inverse of resistance, which is conductance.
Detailed explanation-2: -What is the shape of the graph between V and I, where V is the potential difference applied between the ends of a wire and I is the current flowing through it? Answer: The graph between the potential difference (V) and the corresponding current (I) is a straight line passing through the origin.
