Question

Explain ohm’s law......

Answer 1

Explanation:

Ohm's law that the current through the conductor between two points is directly perportional to the voltage across two points

ohm's law formula

= V = IR

Answer 2

Hola mate

Here is your answer -

Ohm's law states that the current through a conductor is directly proportional to the voltage across the conductor. This is true provided the temperature (and other physical factors) remain constant. The constant of proportionality, R,R is the resistance and has units of ohms, with symbol \Omega,Ω. The relationship can be written as:

V, equals, I, R.  

V=IR

where V,V is the voltage across the conductor and I,I is the current flowing through it. The value of resistance in an ohmic component must be independent of current and voltage. In some small components, increasing the current raises the temperature, and we can't be sure whether Ohm's law is obeyed or not. An example of this is the filament light bulb, in which the temperature rises as the current is increased. Here, Ohm's law cannot be applied. If the temperature is kept constant for the filament, using small currents, then the bulb is ohmic.

The definition of resistance is R, equals, V, slash, I,R=V/I, which allows you to calculate a value for R,R under changing conditions of current and temperature. But if R,R remains constant, then Ohm's Law is followed.
