Answer: 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.
On which principle does the electric iron work?
An electric iron is based upon the principle of heating effect of current. This principle states that when an electric current is passed through a conductor, it generates heat because of the resistance present in it.
How does an electric heater of an electric iron work?
Irons are rather simple in how they work. They work like an electric heater. They have a heating element made out of a metal alloy that gets hot when electricity is applied. … The current through the iron’s heating element generates heat according to the formula Power = Current^2 * Resistance.
Which heating element is used in the electric iron which works on the principle of heating effect of electric current?
Explanation: It has wire named nichrome which is used as a heating element.
Which effect of electric current is used in electric iron?
Answer: Heating effect is the effect that is used in electric iron . It is the rate of flow of charge through any conductor . It is denoted by “I”.
Which effect of electricity is applied in an iron?
An electric iron is based on the principle of the heating effect of current. When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called the heating effect of current. Answer verified by Toppr.
What is automatic electric iron?
When it comes to an automatic electric iron, the thermostat is the most important item. It uses a bimetallic strip to operate the switch which is connected in series with the resistance (or) heating element. The bimetallic strip is a simple element which converts a temperature change into mechanical displacement.
What is the heating element of an electric iron made up of?
So, from all the given Nichrome is used as a heating element in electric iron which is an alloy consisting 80% of Nickel and 20% of Chromium melting point of this element is 1400 degree Celsius with high resistance which makes this element best for using as a heating element.
Which metal is used in electric iron?
Nichrome is used as a heating element in an electric iron. It is an 80 per cent nickel and 20 per cent chromium alloy with nickel and chromium. It has a high melting point of 1400 degrees C.
Why does an electric fuse in the electric circuit melts when large current flows through it?
When an excessive current flows in the circuit, it generates heat in the circuit which leads to melt the fuse due to its low melting point, and it also opens the circuit. The excessive flow of current may lead to breakdown of the circuit and stop the current flow.
When a bulb is fused the electric current?
Hint: When the filament of a bulb is broken then the bulb is said to be fused. When it gets fused it does not emit light. When the bulb gets fused, the electric current is not allowed to pass through the filament and the bulb does not glow because the filament of the bulb is broken.
Which effect of current is used in fuse wire?
Therefore, the fuse is based on the heating effect of current.
Which effect of electric current is used in electric heater and electric iron?
Higher the resistance, the electric current will generate higher amount of heat. Thus, generation of heat by electric current while passing through a conductor is an inevitable consequence. This heating effect is used in many appliances, such as electric iron, electric heater, electric geyser, etc.
When electric current flows through a conductor the conductor becomes?
When an electric current flows through a conductor, it becomes hot because,the resistance of the conductor blocks the electricity flow by making collision of free electrons with the atoms and impurities. This collision produces heat energy.
