When current is plotted against the applied potential, a straight line plot is obtained. Which of the following law is verified?
Ohm's law
Concept used: Electric current
Prerequisite: Knowledge of electrical resistance
According to Ohm's law, the potential difference across a metallic conductor depends on the resistance of the conductor, and the current supplied to the conductor. The expression can be written as,
Here, V is the voltage, R is the resistance, and I is the current,
The expression is a straight line equation where resistance is the slope of the line.
When a plot of voltage against the current is made, then a straight line will be obtained. Therefore, Ohm's law will be satisfied if a plot between voltage and current is made.
Fleming's law, Faraday's law, and Maxwell's law are related to the magnetic field and magnetic flux. Therefore, these options are incorrect.
Hence, option (b) is correct.
