Answer 1

$\huge \fbox \pink{❥Answer࿐}$

Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is 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

Explanation:

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

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:

I=V/R

R=V/I
