Question

Is resistance constant in Ohm's law?

Answer 1

Ohm's law

According to Ohm's law, the voltage or potential difference between two points is proportional to the current of electricity going through the resistance.

1. The resistance of the circuit is proportional to the voltage or potential difference between the two locations. Ohm's law is represented by the formula$V=IR.$
2. If the temperature remains constant, Ohm's law asserts that the current flowing through a conductor is proportional to the voltage across the conductor.
3. The resistance, denoted by the symbol $O$, is the proportionality constant $R$. It is measured in ohms.
4. To obey Ohm's law, a material's resistance must be constant, which means the current and potential differences must be proportionate to each other.

Hence, resistance is constant in ohm's law.
