The formula you
are looking for is W = A x V. Watts = Amps x Volts.

Is a drill a lever?
No, a drill is not considered as a lever.
How power is transferred from drill spindle to drill shank?
Power is transmitted between the drill spindle and drill shank through friction drive (Taper shank push fitted into spindle taper)
What simple machine is used in a hand drill?
A common HSS drill bit.
Where is the simple machine wedge on a drill?
The wedge on a drill is the cutting edges on the end of the drill bit. The sharp edges grab and "wedge into" material to remove it.
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

The formula you are looking for is W = A x V. Watts = Amps x Volts.
How many watts does an electric drill use?
To figure that out you need to know the Amperage that it draws and what the voltage of the circuit is that you're using. Once you know that you can figure out how many watts it uses by doing simple math. Voltage x Amperage = Watts
How many watts of power does does an electric drill use when it is plugged into 120 volts and draws 10 amps?
Power = Volts * current [p = E*I]; 120volts*10amps = 1200watts
How do you decrease rpm of the drill so that it draws less current from 4Amp to 1 Amp I want it to run very slowly?
It sounds like you need a variable speed drill. There was an item on the market a few years ago that you could plug your drill into and control its speed. I haven't seen one lately since most new drills have variable speed built into the drill. On a drill press all you need to do is move the drive belt to the smallest pulley on the motor and the biggest pulley on the drill spindle.
Why will an electric drill operating on a very long extension cord not rotate as fast as one operated on a short cord?
It is the voltage drop from the undersized wire that is used in the extension cord. Under this condition you will find that the drill will start to become hot with the additional current that the drill is trying to draw to keep the motor turning. It could get to a point where the breaker will trip before the drill burns out.
Can you use a Craftsman drill 19.2 volt battery in a 18 volt drill?
The bulb will light but it will be brighter that the wattage rating of the bulb. The higher voltage will shorten the life of the bulb by a very appreciable amount. It is not recommended to do.
What would most reduce current us reliance on foreign imports of oil?
Drill here drill now
What is the common voltage for a cordless drill battery cell?
They used to be either Ni-Cd or NiMH, which made the cell voltage 1.2V. These days they can be Li-Po / Li-Io, which have about 3.6V cell voltage.
What projects should one use a 24v drill for?
A 24v drill is generally used for light domestic or D.I.Y. jobs around the home. When working with concrete, reinforced concrete, or stone, a higher voltage drill may be required.
What would happen to an electric motor if the amount of current in the motor was reduced?
Depends on what sort of motor it was. If it was the sort you find in an ordinary electric drill, then it would slow down. But rememer, the only way you can reasonably reduce the current in to motor is to reduce the voltage in the supply. A motor takes what current it can, dependent on Ohm's Law. To reduce the current, reduce the voltage. But in a three-phase motor, the speed being dependent on the rotation of the phases, it would more or less stay the same. But this assumes it's not under load. A load would cause it to slow down.
Can anyone tell the power ratings of different appliances?
attach at the back portion of the applianceAnswerAll appliances must have a label attached to them, indicating their rated voltage and rated power. For example, this information will be printed on the globe of an incandescent lamp, or somewhere inside the door of a fridge, or moulded onto the plastic body of an electric drill, etc.
Can a rotating masonry drill bit adjacent to a cable create a magnetic field and could it disrupt the electrical current within the cable?
No, a rotating masonry drill bit adjacent to a cable will not create a magnetic field and no it could not disrupt the electrical current within the cable .
