define ohm's law write its mathematical expression to.what are the factors which affect the resistance of a conductor
Answers
★ Define ohm's law?
→ Ohm’s law basically 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.
★ Ohm's law formula :-
→ V = IR or Voltage = Current × Resistance.
→ The SI unit of resistance is ohms and it is denoted by Ω.
→ Basically this law help us to calculate the power, efficiency, current, voltage, and resistance of an element of an electrical circuit.
★ Factors on which the resistance of a conductor depends :-
→ Area of cross section or we can say thickness of wire.
→ Nature of the material.
→ The length of the wire.
