Case study:-

ECE-131

Purpose of studyThe purpose of the case study is to explain:

✓What are electrical devices?

✓What are electronics devices?

Electrical devices➢Electrical devices are defined as

devices that use or generate electricity and transform it into another form of energy, such as motion, heat or light.

➢Examples of electrical devices:-fan heater, ceiling fan, toaster, etc.

Electronic devices➢ An electronic component is any basic discrete device or

physical entity in an electronic system used to affect electrons or their associated fields. Electronic components are mostly available in a singular form and are not to be confused with electrical elements.

➢ Electronic components have two or more electrical terminals (or leads) aside from antennas which may only have one terminal.

➢ Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices.

➢ Examples:- smartphones, headphones, camera, landline.

ceiling fanCeiling fan is a Single phase Induction motor. Generally we use a capacitor start & run AC Motor for ceiling Fans.

Working principle: whenever current carrying conductor is placed in a magnetic field-it experiences force. AC motor needs a rotating magnetic field in order to turn the rotor shaft. In a single phase system capacitor is used to provide a phase shift in the windings of the motor.

Electrical devices used at home

Ceiling fan Fan heater

Toaster▪The electric current flows through a series of thin filaments

connected together but spaced widely enough apart to toast the whole bread surface.

▪The filaments are so thin that they glow red hot when the electricity flows through them.

▪Like a series of small radiators, the filaments beam heat toward the bread in the toaster.

▪The steady supply of heat rapidly cooks the bread. There are filaments on each wall of the toaster so the two sides of the bread cook at the same time.
