Why is the voltage at the end of a long extension lead used with an electric drill less than the mains supply voltage?

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.

How did the electric drill come to be invented?
Wilhelm Fein invented the portable electric drill in 1895.
What was used before the electric drill?
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.
Why was the electric drill invented?
Because they needed something other than hands, to drill rock and dig coal.
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.
How durable is this drill?
An average electric drill will last for about five to ten years, allowing for standard wear and tear and assuming typical usage.
Why will an electric drill operating on a very long extension cord not rotate as fast as one operated on a short cord?
A very long extension cord will have higher resistance, which leads to voltage drop along the cord. This results in lower power reaching the drill motor, causing it to rotate slower compared to when using a shorter cord with lower resistance.
What does electric hand drill mean?
An electric or battery drill that you hold in your hands.
What is the meaning of electric drill?
Portable and electric are adjectives describing the drill, a device for boring holes.
What is the purpose of a battery in a power drill?
To supply the power to the drill.
What is drill machnie?
A drill machine can mean a hand held electric drill, or a bench drill press or a pillar drill.
What are the parts and components of a cordless electric 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
Is hand gloves needed while using electric drill?
No, gloves are not necessary while using an electric drill.
How do you get kinetic energy out of the electric drill?
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.
How do you remove a drill bit from an electric drill?
Normally with a chuck key.
How big should you drill your electric chase?
Drill using a 280 degree drill by samsung drill and drill about 5cm by 5 cm
How did the electric drill come to be invented?
Wilhelm Fein invented the portable electric drill in 1895.
How many watts does an electric drill use?
The power consumption of an electric drill can vary depending on the size and type of the drill. On average, a corded electric drill typically uses between 500 to 1,000 watts. It's always recommended to check the specific wattage information provided by the manufacturer for accurate details.
