What conductor obeys Ohm’s law? – Ohm’s Law state that the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions, such as temperature, remain constant. A conductor that obeys Ohm’s Law is called an ohmic conductor. Copper or constantan wire are examples of ohmic conductors.

#### Which type of conductors obey Ohm’s law?

Ohmic conductors:(A). Obey Ohm’s law(B). Do not obey Ohm’s law(C). Sometimes obey Ohm’s law(D). None of these Answer Verified Hint: Define Ohm’s law. Ohm’s law gives us the relation between the voltage, resistance and current in any DC electrical circuit.

- Obtain the electrical components which follow Ohm’s law and which don’t.
- Define how they work if they don’t follow Ohm’s law.
- Complete step by step answer: Ohm’s law can be defined as, at a constant temperature the electrical current flowing through a conductor is directly proportional to the potential difference applied across the conductor and inversely proportional to the resistance.If V is the potential difference and I is the current flowing, then$\begin & V\propto I \\ & V=IR \\ \end $Where R is the proportionality constant called the resistance of the conductor.The conductors which obey ohm’s law have a constant resistance when we vary the voltage across them or if we increase the current flowing through them.

These types of conductors are called ohmic conductors.In some conductors the resistance varies as we change the temperature. They do not obey ohm’s law. These types of conductors are called non-ohmic conductors.So, ohmic conductors obey Ohm’s law.The correct option is (A).

- Additional information: Mostly we use ohmic conductors but non ohmic conductors also have many applications in our day to day life.
- In a light bulb even if the voltage is increased, the current through the filament still remains constant.
- This is because the voltage increases the temperature of the filament increases which increases the resistance of the filament.

So, the temperature will remain constant and it doesn’t follow Ohm’s law.Note: In an ohmic conductor the graph between the voltage and the current flowing will be a straight line because they obey the ohm’s law. If we consider a non-ohmic conductor the graph between the voltage and current flowing will not be straight line. : Ohmic conductors:(A). Obey Ohm’s law(B). Do not obey Ohm’s law(C). Sometimes obey Ohm’s law(D). None of these

## What is Ohm’s law in electrical circuits?

The video about conductance, resistance, and ohm’s law – Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Ohm’s law is used to validate the static values of circuit components such as current levels, voltage supplies, and voltage drops.

No. Ohm’s law is not a universal law. This is because Ohm’s law is only applicable to ohmic conductors such as iron and copper but is not applicable to non-ohmic conductors such as semiconductors. Ohm’s law doesn’t apply to semiconducting devices because they are nonlinear devices. This means that the ratio of voltage to current doesn’t remain constant for variations in voltage.

Ohm’s law fails to explain the behaviour of semiconductors and unilateral devices such as diodes. Ohm’s law may not give the desired results if the physical conditions such as temperature or pressure are not kept constant.
