Ohm's Law (V=IR)

Ohm's Law

Ohm's Law states that the current through a conductor between two points is directly proportional to the potential difference across the two points.

Mathematical form of Ohm's Law:

$V=IR$ Where V = Potential Difference across the two points and I= current between the two points.

$V=IR$ can also be written in numerous number of ways:

$I = \dfrac{V}{R}$ or $R =\dfrac{V}{I}$ for various calculation purposes.

Ohm's Law

Ohm's Law states that the current through a particular conductor between two points is directly proportional to the voltage (electrical potential) difference between the two points, and is inversely proportional to the resistence of the conductor between the same two points.

Formula for Ohm's Law:

The Most common form of Ohm's Law is expressed as $I=V/R$, where $V$ = Voltage Difference across the two points, $I$ = current between the same two points and $R$ = the resistence of the conductor between the two points.

But a more illustrative form of Ohm's Law is writen as $I=\Delta V/R$ instead, which emphasize the potential difference as the key driver of the current, instead of the voltage (electrical potential) itself. It also shows resistence is the key factor that reduces the current.

This is quite analogous to $a = F_{net}/m$, where the net force is the key driver of the motion, while mass (inertia) is the key factor that reduces the change of movement.

Application of Ohm's Law:

To apply the law, the following forms are frequently used for various calculation purposes: : $\Delta V=IR$ or $R =\dfrac{\Delta V}{I}$, but we should treat them as convenient algebraec ways to organize conditions and unknowns of the problems, not as replacement of the basic form of the law.

According to ohm's law, the current through a current carrying conductor is directly proportional to the potential difference across its ends, given that the physical conditions and temperature remain the same. This the most simple answers. please like it
