Question

state and explain ohms law​

Answer 1

$\huge \mathtt \green{Answer : -} \over$

Ohm's Law : -

Ohm’s Law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the temperature and other physical conditions remain unchanged.

Mathematically it can be represented as,

Potential difference ∝ Current

V ∝ I

( When the value of V increases the value of I increases simultaneously)

V = IR

Where,

V is Voltage in volts (V)

R is Resistance in ohm (Ω)

I is Current in Ampere (A)

Answer 2

Ohm's Law

The current flowing in a conductor is directly proportional to the potential difference of the conductor at its two ends.

Mathematically,it is expressed as:

$\mathrm{V \propto I} \\ \\ \implies \boxed{\bold{V = IR}}$

Resistance

That property of the a conductor that obstructs and opposes the flow of electrons or any charged particle is known as Resistance

• It depends upon length of the resistance. It is directly proportional to the length of conductor » $\sf{R \propto L}$

• It is inversely proportional to the area of cross section » $\sf{R \propto \frac{1}{A}}$

• It also depends upon the temperature and nature of the material of the conductor
