Electrical energy is the energy derived from electric potential energy or kinetic energy of charged particles.

• Electrical energy is the energy that is associated with the flow of electric charge.

• It can be converted into other forms of energy such as mechanical, thermal, or light energy.

• Examples include the energy used to power electrical devices like light bulbs, refrigerators, and computers.

An electronic device is a device that operates using electronic circuits and components to perform various functions.

• Operates using electronic circuits and components

• Performs various functions

• Examples: smartphones, laptops, tablets, TVs, digital cameras

An induction motor is a type of AC motor where power is supplied to the rotor by electromagnetic induction.

• Induction motors are commonly used in various applications such as industrial machinery, pumps, fans, and compressors.

• They do not require any physical connection between the rotor and the stator, making them more reliable and maintenance-free.

• The speed of an induction motor is determined by the frequency of the AC power supply and the number of poles in the motor.

• Inducti...read more

Resistance is the opposition to the flow of electric current in a material.

• Resistance is measured in ohms (Ω).

• It is caused by collisions between electrons and atoms in a material.

• Materials with high resistance are insulators, while those with low resistance are conductors.

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.
