Question

What is the Ohms law.

Answer 1

Answer:

DEFINITION

Definition of Ohm's law. : a law in electricity: the strength of a direct current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit.

EXAMPLE

This is called Ohm's law. Let's say, for example, that we have a circuit with the potential of 1 volt, a current of 1 amp, and resistance of 1 ohm. Using Ohm's Law we can say: ... The amount of water in the tank is defined as 1 volt and the "narrowness" (resistance to flow) of the hose is defined as 1 ohm.

3 FORMS

electrical circuit, the current passing through most materials is directly proportional to the potential difference applied across them. Fig. 3-4: A circle diagram to help in memorizing the Ohm's Law formulas V = IR, I = V/R, and R= V/I. The V is always at the top.

Answer 2

Ohm's Law :

Ohm's law states that the current (I) passing through a conductor is directly proportional to the potential difference (V) across its ends, provided the physical conditions like temperature, density, etc. remains unchanged.

Mathematically :

Potential difference ∝ Current

or

Potential difference = Resistance × Current

or

V ∝ I

or

V = RI

Here, Resistance (R) is a constant.⠀ ⠀⠀ ⠀ ⠀⠀ ⠀

@ItsFadedStar booster :

Resistance : It is a property of conductor by virtue of which it opposes the flow of current through it. It is equal to the ratio of the potential difference applied across its ends and the current flowing through it

$\sf Resistance = \dfrac{Potential \: difference}{Current}$

or

$\sf R = \dfrac{V}{I}$
