Question

how Om's law do work​

Answer 1

Answer:

Probably the most important mathematical relationship between voltage, current and resistance in electricity is something called “Ohm's Law”. This formula is used to calculate electrical values so that we can design circuits and use electricity in a useful manner.

Answer 2

Answer:

V=IR

Explanation:

Through various exprements it came to our sense that when the voltage(V) increases current(I) increases too.

hence, V is directly proportional to I.

now to remove the proportional sign we must add a constant. In our case it is R.

V=I×R

here R is resistance.

this is known as Ohm's Law.
