Which is not correct in the case of electric fuse?

Fuse is designed to limit the maximum current. There is a maximum limit of current above which the fuse blows and the circuit is broken. Option (c) – This is incorrect. There is only a limit on the maximum current, not on minimum current.

What is an electric fuse answer?

Answer: An electrical fuse is a low melting point copper or other metal wire that breaks due to heat caused by overvoltage or high load to avoid short circuit or failure to the device.

What is in an electrical fuse?

The fuse element is made of zinc, copper, silver, aluminum, or alloys among these or other various metals to provide stable and predictable characteristics. The fuse ideally would carry its rated current indefinitely, and melt quickly on a small excess.

Which effect is used in electric fuse?

The electric fuse works on the principle of the heating effect of electric current. It consists of a piece of wire made of a metal or an alloy of low melting point. As the current increases beyond a limit, the wire in the electric fuse melts and breaks off.

What is the proper place of fuse in electric circuit?

The best place to install a fuse in a grounded power system is on the ungrounded conductor path to the load. That way, when the fuse blows there will only be the grounded (safe) conductor still connected to the load, making it safer for people to be around.

What is electric fuse Class 7?

Fuse is a safety device that is a safeguard to all of our electrical appliances. They are made up of special material which melt quickly and break when large electric currents passed through it.

What is electric fuse in Brainly?

Explanation: An electric fuse is a safety device used to limit the current in an electric circuit. The use of a fuse is to safeguard the electric circuit and the electric appliances connected in the electric circuit from being damaged.

What are the 3 types of fuses?

Different Types of Fuses – Constriction, Working & Characteristics

  • DC Fuses.
  • AC Fuses.
  • Cartridge Fuses.
  • D – Type Cartridge Fuse.
  • HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse.
  • High Voltage Fuses.
  • Automotive, Blade Type & Bolted Type Fuses.
  • SMD Fuses (Surface Mount Fuse), Chip , Radial, and Lead Fuses.

How are electric fuses made?

A fuse consists of a low resistance metal wire as fuse element, a small cross-section compared to the circuit conductors mounted between a pair of electrical terminals. It is enclosed in a non-combustible tube which is surrounded by a filler material which may be sand or other material.

What are the features of a fuse?

The fuse element is generally made of materials having low melting point, high conductivity and least deterioration due to oxidation e.g., silver copper etc. It is inserted in series with the circuit to be protected. Under normal operating conditions, the fuse element is at a temperature below its melting point.

What are the four effects of electric current?

Name four different effects of electric current?

  • Magnetic effect.
  • Chemical effect.
  • Heating effect.
  • Electric shocks.

Which case HRC fuse provides best protection?

HRC fuse provides best protection against

  • Open circuit.
  • Overload.
  • Reverse current.
  • Short circuit.

Why fuse is used in electric circuit?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily.
