electrical energy into chemical energy
Transformer is a electromagnetic stationary device which converts electrical energy from one level to another level by keepings its frequency constant. Whereas in motors or generator electrical energy is converted to mechanical energy and vice versa. Now when this conversion of energy is taking place noise and friction comes in existence due to which some loss of input energy takes place due to which energy output reduces and efficiency accordingly.
For all practical purposes, we are still limited by wireswhen we need to move electrical energy.
This seems like a question from an electrical course, and is probably best answered by referring to your course materials. It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.
Electrical Power equation: P = I x V (Electrical power = Current x Potential Difference) Hence if one has a Current in Amps (A) and a Potential Difference in Volts (V), these two values multiplied together give the size of the electrical power, P in Watts. 1 Watt is also equivalent to 1 Joule per second. Hence the units Watts maybe replaced by J/s or Js-1. Also, Using Ohms Law V = I x R (Potential difference = Current x Resistance) The electrical power equation maybe re-written: P = I x I x R = I2 x R = I2R (using V = I x R) or P = (V/R) x V = V2 / R (using I = V/R)
Electrical to mechanical energy conversion takes place in a motor. The motor uses electricity to generate rotational motion, which can then be used to drive various mechanical systems.
In an electrical motor, electrical energy is converted into mechanical energy to produce motion. In a galvanometer, electrical energy is converted into mechanical movement of the pointer in response to the flow of current.
In an electric motor, electrical energy is converted into mechanical energy to produce motion. In a generator, mechanical energy is converted into electrical energy by rotating a coil within a magnetic field. Essentially, electric motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.

Energy conversion takes place when one form of energy is converted to another form. An example would a turbine, which converts heat energy to mechanical energy, or a generator which converts mechanical energy to electrical energy, or an electric motor which converts electrical energy to mechanical energy. In all conversion processes energy is lost (i.e. it is converted to heat at a low temperature). The useful power output of a machine is always less than the power input, by a ratio called the efficiency, usually expressed as a percentage. Typical efficiency for an electric motor is 95%, for a car engine 25%.
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
In an electric motor, electrical energy is transformed into mechanical energy. This is achieved through the interaction between an electric current and a magnetic field, which causes the motor to produce rotational motion.
In an electric fan, electrical energy is converted into mechanical energy and thermal energy. The electrical energy powers the motor in the fan, which then rotates the blades to create air movement. Some of the electrical energy is also dissipated as heat during this conversion process.
Electrical energy is converted into kinetic energy. It makes motor mouse move.
Energy conversion takes place in a flashlight when the electrical energy from the battery is converted into light energy and heat energy through the process of powering the light bulb or LED. This conversion occurs instantly when the circuit is completed and the flashlight is turned on.
When using a torch, electrical energy is converted into thermal energy and light energy. The electrical energy is used to heat a filament inside the bulb, which then produces both heat and light.
