What is an over-current protective device?
That is called a fuse. A fuse is a protective device, which will interrupt the flow of electricity if it is subjected to a current that is greater than its rating. Some fuses are designed to handle a large inrush of current and are used in circuits such as air conditioners, where a large amount of current is needed at startup, for a short duration and then current drops to a lower level. These are sometimes called time-lag fuses.
What is an object called that melts under high voltage to protect circuits?
A device that melts under high current , not high voltage is a circuit protective fuse. There are many fuses that are rated for voltages in the 10,000 volt range. It is the over current that trips them.
What is the purpose of a current limiting resistor in a diode circuit?
Diodes are rated to use a certain amount of current. If you go over that amount, it will eventually destroy the device, how long it takes to destroy the device depends on how much more current you are running through it than it is rated at.
What are the disadvantage of a circuit breaker or a fuse in a circuit?
The only ones that could affect that decision to put one in is if you're planning on smoking or blowing-up that item in the circuit, or the hassle of changing a 20 cent - 5 dollar item instead of the more expensive item.
What is a over current trip relay?
It is the one type of coil in the electrical motor starters. It is used to release the switch, i.e. turns off the motor, when heavy load is connected to the motor. It is used for the protection purpose.
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.

What protect equipment from too much current by tripping a switch that breaks the current by stopping the flow of electricity?
In electrical terminology it is an over current device. This could be an electrical breaker. Another form of an over current device is a fuse.

What is protective democracy?
a device through which citizens could protect themselves from the enroachments of government hence protective democracy.
What is over voltage relay?
A protective device that operates when voltage exceeds nominal by some set amount. These are often coupled with a timer.
