It is the ohm.


Who formulate the inverse of ohm?

The inverse of Ohm's law, which relates voltage, current, and resistance, can be expressed as ( I = \frac{V}{R} ) where ( I ) is current, ( V ) is voltage, and ( R ) is resistance. While Ohm's law itself was formulated by Georg Simon Ohm in the 19th century, the inverse relationship is a natural mathematical consequence of his original formulation. Therefore, it is not attributed to a specific individual but rather stems from the application of Ohm's law.


Who discovered the mathematical law of electrical current?

Are you talking about Ohm's Law. Voltage = (Current) x (Resistance). Georg Ohm


How does the steepness of the graph relate to the resistance?

The steepness of a graph, particularly in a voltage-current (V-I) graph, indicates the resistance of a circuit element according to Ohm's Law (V = IR). A steeper slope signifies higher resistance, as it shows that a greater voltage is required to produce a given current. Conversely, a less steep slope indicates lower resistance, meaning less voltage is needed for the same current. Thus, the slope of the graph inversely reflects the resistance: steeper slopes correspond to higher resistance values.


Which resistor is the better insulator 24 or 6?

The resistance value of a resistor indicates how well it can insulate against the flow of electric current. A 24-ohm resistor has a higher resistance compared to a 6-ohm resistor, meaning it is better at restricting current flow and thus acts as a better insulator. Therefore, the 24-ohm resistor is the better insulator.

What is ahigher resistance 10 ohm or 1 kilo ohm in other words does 1kilo ohm have more or less resistance than 10 ohm.?

Because 1 kiloohm is 1000 ohms. 1000 ohms is a higher resistance value than 10 ohms.


What is resistance if less than 1 ohm?

1 Ohm represents nearly no resistance to current flow, at all. The word, Ohm is usually capitalized as it comes from a person's name.


Why watt density too high mega ohm is low?

ohm's measure resistance, the more ohm's the more resistance the less voltage


Why insulation resistance is given in mega ohm?

If it were less than a number of Megohms it would not be insulation.

What equipment is used to test if armature is shorted?

An ohm meter.


What SI unit is used to measure resistance?

The units for resistance is Ohm (Ω).The standard unit of resistance is the ohm (with a lower case 'o'), named after the German physicist Georg Simon Ohm.


Is an 8 ohm sub woofer better than a 4 ohm sub woofer?

no the higher the ohm the more resistance in the speaker the lower the resistance the more power it will use so if they are the same make the 4 ohm should be louder


Set up 2 4 ohm sub to 2 ohm?

If you are trying to pump a 2.4 ohm sub with a 2 ohm rated amplifier you should be fine. The rating on the amplifier is the least resistance it should have on its load. Anything less than 2 ohms would fry your amp.


What does ohm sign symbolize?

The ohm is the unit of electrical resistance to current flow. More ohms (more resistance), the less current will flow. Less ohms (less resistance), the more current will flow. One ohm is defined as the amount of resistance that will cause one ampere of current to flow if the supply voltage is one volt. Ohm's law states that amps = volts / ohms So, if you had a 12 volt battery, and you connected a load, say a heating element that had a resistance of 3 ohms, how much current would flow in the circuit? amps = 12 volts / 3 ohms amps = 4
