Question

ohm's law ?


circuit diagram ...​

Answer 1

Answer:

Explanation:

according to ohms law the potential difference across the conductor is directly proportional to current flowing through its end .

i.e.  V ∝ I

⇒V/I  equal to R

⇒ V ≡ IR

Answer 2

ANSWER

Ohm’s law states the relationship between electric current and potential difference. The current that flows through most conductors is directly proportional to the voltage applied to it. Georg Simon Ohm, a German physicist was the first to verify Ohm’s law experimentally.

Ohm’s Law Explanation

One of the most basic and important laws of electric circuits is Ohm’s law.

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant.

Mathematically, this current-voltage relationship can be written as,

$\tt{V=IR}$

In the equation, the constant of proportionality, R is Resistance and has units of ohms, with symbol Ω.

The same formula can be rewritten in order to calculate the current and resistance respectively as follows:

$\tt{I= \frac{V}{R} }$

$\tt{R = \frac{V}{I} }$

Ohm’s Law Statement:

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature, remain constant.

Ohm’s Law Equation: V = IR, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.

Experimental Verification of Ohm’s Law

Ohm’s Law can be easily verified by the following experiment:
