As the electrical energy is used to run blades in the mixer grinder and hence we say in mixer grinder electrical energy is transformed into mechanical energy

Explanation:

When electrical energy is transformed into mechanical energy, it means that electricity is being used to create movement or perform work. One common example of this transformation is seen in a mixer grinder.

Mixer Grinder:
A mixer grinder is a kitchen appliance used for blending, grinding, and mixing ingredients. It consists of an electric motor and a set of rotating blades or jars. When the motor is switched on, electrical energy is supplied to the motor, which then converts it into mechanical energy.

Working of a Mixer Grinder:
1. Electric Motor: The heart of a mixer grinder is the electric motor. It is typically a universal motor, which can run on both AC (alternating current) and DC (direct current). The motor consists of a stator (stationary part) and a rotor (rotating part).
2. Stator: The stator contains a set of coils that are connected to an electrical power source. When the power is supplied, it creates a magnetic field in the stator.
3. Rotor: The rotor is connected to the blades or jars of the mixer grinder. It is placed inside the stator and can rotate freely. The rotor contains a set of permanent magnets.
4. Electromagnetic Induction: When the electrical power is supplied to the stator, it produces a rotating magnetic field. This rotating magnetic field induces an electromotive force (EMF) in the rotor due to electromagnetic induction.
5. Conversion of Electrical Energy: The induced EMF in the rotor causes it to rotate. As a result, the blades or jars attached to the rotor also start rotating. This rotation is the mechanical energy produced from the electrical energy supplied to the motor.
6. Grinding, Blending, and Mixing: The rotating blades or jars of the mixer grinder can be used to grind various food ingredients, blend liquids, and mix dough or batters.

Conclusion:
In a mixer grinder, the electrical energy is transformed into mechanical energy through the operation of the electric motor. The motor converts the electrical energy into a rotating magnetic field, which then induces an EMF in the rotor. This induced EMF causes the rotor and the attached blades or jars to rotate, resulting in the production of mechanical energy for grinding, blending, and mixing purposes.
