Question

state ohm's law. express it both mathematically and grphically​

Answer 1

Answer:

Hi mate

Here is your answer

Explanation:

The connection between voltage, current, and resistance is illustrated by Ohm's law.

Ohm's laws declare that the current through any two points of the conductor is directly proportional to the potential difference applied over the conductor, given the physical conditions i.e. temperature, etc.

Ohm Law states that when current is passed between two points of a conductor, the current is directly proportional to the potential difference between the two points.

The mathematical formula for Ohm’s Law is V=RI,

where V stands for voltage,

I stands for current and

R represents resistance.

The graph line to represent Ohm Law will be a straight line with V on y-axis and I on x-axis.

Answer 2

$\Large{\underline{\underline{\red{\tt{\overbrace{\underbrace{\dag Ohm's\:\:Law:- }}}}}}}$

Ohm's law states that the if the physical conditions are remain unchanged , the thethe potential difference across the two ends of a conductor is directly proportional to the electrical current flowing through it.

Mathematically ,

$\sf{\implies V \propto I }$

$\bf{\implies V = IR }$

where R is the constant of proportionality and is called the resistance of the conductor it is a property of a conductor to resist the flow of charge through it.

[For V - I graph refer to the attachment: ]

More to know :

• SI unit of resistance is ohm ( Ω ).
• The V-I graph passes through the origin O .
• Resistance of a conductor is directly proportional to the length and inversely proportional to the cross- section area.
• The specific resistance or register beauty of a conductor depends on the nature of the mercy of a substance and not on its shape and size.
• it is defined as a resistance of a wire wire of material of unit length and unit cross section area or we can also define resistivity as the resistance of a unit metre cube of that material.
• The SI unit of resistivity is ohm metre.(Ω-m).
• the conductivity of specific conductance measures of materials ability of a conductor current electrical current and is reciprocal of resistivity.
