Answer:
Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R).
The electrical resistance per unit length, area, or volume.
Resistance is the opposition that a substance offers to the flow of electric current.
Explanation:
V =IR
1ohm is the unit of resistance . It is equal to 1 volt upon 1 ampere. It means that an object having a resistance of 1ohm allows 1 ampere of current to flow through 2 points having potential difference of 1 volt.
