Devices that do not obey Ohm's law are called non-ohmic or non-linear devices. Their resistance changes with the voltage applied or the current flowing through them. Here are a few examples: Diodes: These semiconductor devices allow current to flow primarily in one direction. Their resistance is very high in the reverse direction and low in the forward direction, but the forward resistance also changes with voltage. Transistors: These are also semiconductor devices used for amplification and switching. Their resistance is highly dependent on the control voltage or current. Incandescent light bulbs: As the filament heats up due to current, its resistance increases. This means the voltage-current relationship is not linear. Thermocouples: These devices generate a voltage that depends on temperature. Their resistance characteristics are non-linear. Send me the next one 📸
