Ohmic and non-ohmic conductors are two types of electrical conductors that differ in how they respond to resistance. Here are some key differences between them:
Ohmic Conductors:
- Follow Ohms law, which states that the current flowing in a circuit is directly proportional to the applied potential difference and inversely proportional to the resistance in the circuit.
- Have a constant resistance over a wide range of applied voltages.
- The relationship between current and voltage is linear.
- Examples include metals and resistors.
Non-Ohmic Conductors:
- Do not follow Ohms law.
- Have a resistance that varies with the applied voltage.
- The relationship between current and voltage is not linear.
- Examples include diodes and semiconductors.
It is worth noting that non-ohmic conductors can be useful in a variety of electrical and electronic operations where precise control of current inflow is not necessary, while ohmic conductors are useful in electrical circuits where accurate and predictable control of current inflow is needed.
