Question

Explain how the resistance count?

please any one ​

$\Huge{\textbf{\textsf{{\color{Magenta}{⛄A}}{\red{n}}{\purple{s}}{\pink{w}}{\blue{e}}{\green{r}}{\red{}}{\purple{⛄}}{\color{pink}{:}}}}}$

R stands for resistance in this formula. If resistance is unknown, the formula can be converted to R = E/I (ohms = volts divided by amps). Examples: In an electric heater circuit, as portrayed in the two illustrations below, resistance is determined by measuring circuit voltage and current, then applying Ohm's Law.

Answer 2

Dear, friends :)

=> Resistance :

It is the property of a conductor due to which it opposes the flow of current through it.

Numerically,

Resistance(R)=Potential difference(V)/Current (I)

SI unit=ohm
