Applications of Capacitors, Inductors and Diodes

Capacitors:

Capacitors are used for several purposes:

• Timing - for example with a timer controlling the charging and discharging.

• Smoothing - for example in a power supply.

• Filtering - for example in the tone control of an audio system.

• Tuning - for example in a radio system.

• Storing energy - for example in a camera flash circuit.

 

Inductors:

• Traffic Light Sensors: to detect the car and change the signal from red to green.
• Flittering: to filter out noise in any voice signal.

 

Diodes:

• Light Emitting Diodes
• Rectifier Circuits
• Directing current in one direction only
• Vending Machines
