What energy transformation takes place when an electric drill is used?
Electricity is turned into mechanical rotation.Some of the rotation removes material from the hole while some becomes heat energy.assuming the electric drill has no monitors and has just a drill, and assuming the electric drill is powered by rechargeable lithium ion batteries, things happen in the order below starting with the drill battery charger1. drill charger converts electrical energy into chemical energy and stores it into the lithium ion battery2. when the user pushes the power button of the drill, chemical energy of the lithium ion battery is converted into electrical energy3. the electrical energy is converted into magnetic energy by the coil in the drill motor4. the magnetic energy then converts into kinetic energy and spins the drill head5. when the drill head touches something, part of the kinetic energy is converted into sound energy which we hear, thermal energy is also created when the drill touches something, which is caused by friction
What kind of energy does a toster have?
Input energy: usually electric energy. Output energy: heat.
What is the useful energy from an electric drill?
sound, also heat
What does energy efficiency?
Energy conversion efficiency is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The useful output may be electric power, mechanical work, or heat.
An electric drill transfer some energy wastefully . aside from heat , what else carries the energy that is transferred wastefully?
sound waves
Does an electric drill change electrical energy to kinetic energy?
Yes.

What is the output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
What is output of an electric motor?
An electric motor converts electrical energy to kinetic energy.
Why it is that mechanical energy is the output of an electric motor?
Because that is the purpose on an electric motor.

sound, also heat
Does an electric can opener convert electric energy sound energy?
Not likely - any machine wastes some energy; that would reduce the useful output energy.
An electric drill transfers some energy wastefully. Aside from heat, what else carries the energy that it transfers wastefully?
oio

Why are transformer more efficient than a rotating electric machine?
Transformers inherently do not have frictional losses, but transformers and rotating machines perform completely different functions, so I'm not sure it is fair to compare them. Transformers are used to transform electric energy (the input is electric energy, and the output is electric energy). Rotating machines either take electric energy and convert it to mechanical/kinetic energy, or take kinetic energy and convert it to electric energy.
