Question
What is Ohm’s Law?
Answer
Ohm’s Law is: The electric current I flowing through a substance is proportional to the voltage V across its end, i.e., V ∝ I or V = RI where the constant of proportionality R is called the resistance of the conductor. The SI unit of resistance is ohm, and is denoted by the symbol Ω. The resistance R not only depends on the material of the conductor but also on the dimensions of the conductor as below in the formula:- 1 Ω = 1 VA-1Subscribe to our youtube channel!
