Resistance in the length of wire that makes up the extension cord causes voltage to drop. But it needn't be a problem with the right extension cord. For an electric drill, up to a 25 foot cord of 16 gauge wire will cause a voltage drop so small as to be negligible. For 50 feet, switch to a 14 gauge cord. For heavier power tools (circular saw in particular) you should use a 14 gauge extension from the get-go.
Wilhelm Fein invented the portable electric drill in 1895.
Before the electric drill , it was done by hand. There's a hand-cranked drill, probably still used by the Amish. My father owned one.
Because they needed something other than hands, to drill rock and dig coal.
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.
An average electric drill will last for about five to ten years, allowing for standard wear and tear and assuming typical usage.
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.
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
An electric or battery drill that you hold in your hands.
Portable and electric are adjectives describing the drill, a device for boring holes.
To supply the power to the drill.
A drill machine can mean a hand held electric drill, or a bench drill press or a pillar drill.
There are only a few parts and components that separate a cordless electric drill from a corded electric drill. Having a battery instead of a cord is the biggest difference.ÊÊ
No, gloves are not necessary while using an electric drill.
The size of an electric drill is primarily determined by its chuck size, which indicates the maximum diameter of the drill bit it can accommodate. Common chuck sizes include 1/4 inch, 3/8 inch, and 1/2 inch, affecting the drill's versatility for different tasks. Additionally, the drill's power, measured in amps or voltage, influences its size and performance capabilities. Overall, the combination of chuck size, power, and design features determines the drill's overall size and suitability for various applications.
When you operate an electric drill, the motor inside converts electrical energy into kinetic energy to rotate the drill bit. This kinetic energy is transferred to the drill bit, allowing it to drill holes into the material.
Normally with a chuck key.
In an electric drill, electrical energy from the power source is converted into mechanical energy to rotate the drill bit. This conversion is achieved through the interaction of the electric motor within the drill, which transforms the electrical energy into rotational motion.
