Question

describe the verification of ohm's law withactive​

Answer 1

Explanation:

Resistance is the property of a component which restricts the flow of electric current. Energy is used up as the voltage across the component drives the current through it and this energy appears as heat in the component. Resistance is measured in ohms, the symbol for ohm is an omega(Ω).

mark me as brainliest and follow me.thanks!!!

Answer 2

Objective:

To verify the Ohm's law.

Statement of Ohm's Law:

Ohm’s law states that at a constant temperature, current 'I' through a conductor between two points is directly proportional to the potential difference or voltage 'V', across the two points. That is,

V propto I

or frac{V}{I} = constant = R

or V = IR

Thus, the ratio V : I is a constant. This constant is called as the resistance (R) of the conductor.

Graph:

After performing experiment for different readings of V & I and recording the observations, if we plot current on the x-axis of a graph and voltage on the y-axis of the graph, we will get a straight-line. The gradient of the straight-line graph is related to the resistance (R) of the conductor.

hope it is helpful.
