Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship

Dear Students,

We noticed that some students are copying and pasting same answer that has posted by previous users. Also, they are creating multiple account to post question and then answering those questions & approving as well. Please note that all these activities come under spamming and no gift voucher will be issued to them.

Hope that you will maintain the decorum of this forum and help the students genuinely

The predominant equation which pervades the study of electric circuits is the equation

ΔV = I • R

In words, the electric potential difference between two points on a circuit (ΔV) is equivalent to the product of the current between those two points (I) and the total resistance of all electrical devices present between those two points (R).

this is cslled ohm’s law equation.

ohms law can be stated as follows.

The current density(J) across a conductor is directly proportinal to the Electric field(E) applied across the conductor.

The proportinality constant is Conductivity(Sigma)

ohms law : $J = \sigma E$

V = I R can be deduced from the above equation.

Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

“I” is directly prortional to “v” here= V----->POTENTIAL DIFFERENCE and I=”current “

Ohms law is the besic law in electric current which is given by george simon ohm,
it states that when the equilibrium condition is maintained and with constant temp and pressure the potential diffrence applied across the end of the wire is directly proportional to the electric current .
QUANTITATIVLY , u can say that V IS DIRECTLY PROP TO I
AND BY REMOVING THE proportionality sign u will get the following expression
V=RI
WHERE the symbols have their usual meaning
v= potential diff applied across wire
r= proportionality constant,, resistance (unit- ohm)
i= current flowing in the cross sectional area of wire..
HOPE IT HELPS

AT CONSTANT TEMPERATURE THE POTENTIAL DIFFERANCE APPLIED ACROSS A CONDUCTOR IS DIRECTLY PROPORTIONAL TO CURRENT V=ir

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

Ohm's Law is given by:

V = I R

where V is the potential difference between two points which include a resistance R
