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
An electric drill transfer some energy wastefully . aside from heat , what else carries the energy that is transferred wastefully?
sound waves
What are disadvantages of electric current?
That you spend energy to heat electric lines but not actually for something useful.
What is the efficiency of a motor that converts 100J of electric energy into 70j of useful energy?
70% efficient Take: Useful work out --------------------- X 100 = efficiency Work in
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.
Does an electric drill change electrical energy to kinetic energy?
Yes.

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

What does electric hand drill mean?
An electric or battery drill that you hold in your hands.
What objects have electric energy?
There are many objects that perform electric energy, these are just a few examples. Radio Electric fan motor electric cooker electrical kettle doorbell record player food mixer electrical drill I hope this helped!

How are eletrical energy and llight energy useful to you?
I find electric light particularly useful because when it gets dark the electric light enables me to move around without crashing into the furniture and the walls.
