Question

According to Ohm's law the graph of potential difference and current is _____________.
  1. Circular
  2. Curved
  3. Straight line passing through origin
  4. Line having an intercept on X-axis

A
Straight line passing through origin
B
Curved
C
Line having an intercept on X-axis
D
Circular
Solution
Verified by Toppr

The correct option is A Straight line passing through origin
The current flowing through a resistor at a constant temperature is directly proportional to the potential difference across it. A component that gives a graph like the one to the right is said to follow ohm's law.
