Memristors are non-volatile memory devices that change resistance based on current history. They’re fast, energy-efficient, and useful in neuromorphic computing and ReRAM. Key types include metal-oxide and phase-change memristors.

Heating elements convert electricity into heat, using materials like Nichrome and Kanthal. They are used in appliances and industrial systems. Common issues include burnout and corrosion, but regular maintenance can prolong their life.

Sensors detect changes in physical, chemical, or biological parameters and convert them into electrical signals. They have various types and applications, from industrial to healthcare. Key selection factors include accuracy, sensitivity, and environmental suitability.

RTDs measure temperature by tracking changes in metal resistance. Platinum is used for its stability. They’re ideal for precise temperature control in industries like food and healthcare. Common issues include open circuits and short circuits.

Schottky diodes are fast, low-voltage diodes with minimal power loss, making them ideal for power electronics and rectifiers. They have low forward voltage (0.2-0.4V) and no reverse recovery time but higher reverse leakage. They’re used in applications like phone chargers and solar charge controllers.

Thyratrons are gas-filled tubes used to manage high voltages and currents, commonly in radar, medical, and industrial systems. They work by ionizing gas to create a plasma for current flow. Key issues include misfires and reduced performance, which can be solved with maintenance.

Loudspeakers convert audio signals into sound using components like the cone, voice coil, and magnet. Choose based on use, room size, and budget for optimal performance.

Current sensors detect electric current and convert it into readable signals. Types include Hall effect, shunt, and CT sensors, used in industries like automotive and renewable energy. Key factors for selection are accuracy, sensitivity, and response time.
