Ohm's law states that the current through a conductor is directly proportional to the voltage across the conductor and inversely proportional to the resistance of that conductor.

- [Instructor] What we will introduce ourselves to in this video is the notion of electric circuits and Ohm's law, which you can view as the most fundamental law or the most basic law or simplest law when we are dealing with circuits.

It could also be expressed as Amps = Voltage / Resistance or Resistance = Volts / Amps.

The mathematical formula for Ohm's law is: V= RI where V is the potential difference (in V) R is the resistance (in Ω) I is the current intensity ( in A) This law can also be expressed… Later he generalized it significantly and formalized it better.

Ohm's Law Voltage = Current x Resistance V = I x R Answer There is NO 'Ohm's Law formula'!

Ohm's Law is simply a statement of the relationship between voltage and current in some materials.

Ohm's law, that electric current is proportional to a potential difference, was first discovered by Henry Cavendish, but Cavendish did not publish his electrical discoveries in his lifetime and they did not become known until 1879, long after Ohm had independently made the discovery and published himself. Ohm experimented with optics, acoustics, and the electrical conductivity of liquids, though he didn't achieve any real progress…

If the loads are wired in series, add the three values to get the total R.

For non-linear devices, the ratio continuously changes for variations in voltage.

So, it's questionably whether Ohm's Law should be 'law' at all, and one might wonder why we even bother to teach it!

• ###### Resistance and Ohm's Law; Series and Parallel CourseNotes

Ohm's Law V = IR. The connection between voltage and resistance can be more complicated in some materials. These materials are called non-ohmic. We'll focus mainly on ohmic materials for now, those obeying Ohm's Law. Example. A copper wire has a length of 160 m and a diameter of 1.00 mm. If the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm's Law, V = IR.…
