Who invented safety machine?
The safety pin was invented by Walter Hunt in 1849. Hunt 1795-1859) patented the safety pin on April 10, 1849 (patent No. 6,281). Hunt's pin was made by twisting a length of wire. Hunt invented the safety pin in order to pay a debt of $15; he eventually sold the rights to his patent for $400.
Why was the safety pin invented?
The safety pin was invented to pay off a debt.
In three pin switch why earth pin is made bigger in size?
The earth pin is longer in a three pin plug so that when being plugged it it makes contact to ground the equipmemt before the other pins make the equipment live. If the equipment has a fault, the earth circuit is already in place to deal with it.
What year was safety pin invented?
Walter Hunt was granted a US Patent #6,281 for a safety pin on April 10, 1849.
Why is safety pin an conductor?
A safety pin can conduct electricity because it is made of metal, which is a good conductor of electricity. When a voltage is applied across the safety pin, electrons are able to flow through the metal, allowing electricity to pass through.
Is a safety pin made of cells?
No it is not made of cells it is dead a safety pin is not alive
Is a safety pin a conductor?
Yes, a safety pin is a conductor. It can carry an electric current and allow it to flow between two points. This is because safety pins are typically made of metal, which is a good conductor of electricity.
How much is a metal pin?
The cost of a metal pin depends on the metal it is made out of. The cost also depends on the amount of metal used in the pin.
Is a safety pin a conductor or insulator?
A safety pin is a conductor because it allows electricity to flow through it. The metal material of the safety pin allows for the movement of electrons, making it a good conductor of electricity.
What year was the safety pin made?
The modern safety pin was invented by mechanic Walter Hunt in 1849.
Can a safety pin be a conductor is placed on battery?
Yes, a safety pin can conduct electricity if it is placed on a battery. The metal in the safety pin can act as a conductor, allowing the flow of electrons from the battery through the pin. However, care should be taken when using a safety pin in this way to avoid any short circuits or accidents.
When was the safety pin made?

When was the first safety pin made?
1890
Is a safety pin an insulator or conductor?
A safety pin is a conductor because it allows electric current to flow through it due to its metal material, which is a good conductor of electricity.
Is an safety pin a insulator?
No, a safety pin is not an insulator. It is a conductor of electricity due to its metal composition, which allows electric current to flow through it easily. Insulators, on the other hand, are materials that do not conduct electricity.
What metal is a bobby pin made out of?
Steel. (Usually has a coating, but the metal is steel)
