Question

State Ohm’s law. Also define resistance.​

Answer 1

Answer:

Answer is below!

Explanation:

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. The SI unit of resistance is ohms and is denoted by Ω This law is one of the most basic laws of electricity.

Resistance is the opposition that a substance offers to the flow of electric current.  It is represented by the uppercase letter R.  The standard unit of resistance is the ohm, sometimes written out as a word, and sometimes symbolized by the uppercase Greek letter omega Ω.

Answer 2

Answer:

OHM'S LAW

Ohm’s law states that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperature remain constant.

Ohm’s Law Equation:

V = IR,

where, V is the voltage across the conductor,

I is the current flowing through the conductor and

R is the resistance provided by the conductor to the flow of current.

RESISTANCE

Resistance is the opposition that a substance offers to the flow of electric current.

SI UNIT of Resistance is Ohm (Ω).

Ohm => When an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm.
