Question

explain in brief Ohm's law

Answer 1

HEYA!!!


HERE IS YOUR ANSWER,


> Ohm's Law is the mathematical relationship among electric current, resistance, and voltage.

> Mathematically, Ohm's Law for DC circuits can be stated as three equations:

=> V = IR .......1)

=> I = V/R .........2)

=> R = V/I .........3)

> According to this law, the amount of electricity passing through a conductor between two points in a circuit is directly proportional to the voltage across the two points, for a particular temperature.

> Ohm’s law may not hold true all the time. Experiments have proved that some materials behave in a non-ohmic way when weak electric field is applied to them.

✔✔This law was given by a German physicist Georg Simon ohm in the year 1827.

✨✨ It gives a relationship between current, flowing in a metallic wire and potential difference across its terminals.

➡➡ ACCORDING to this law,
$the \: electric \: current \: \\ flowing \\ \: through \: a \: conductor \: \\ is \: \\ directly \\ \: proportional \: to \: the \: potential \: differnce \: \\ applied \:across \: its \: ends \: providing \: \\ the \: physical \: conditions \: \\ such \: as \: temp \: remain \: unchanged \:$



MATHEMATICALLY,

V= IR

I= V/R
