When we switch on a light bulb, it is due to the heating effect of electric current, and when we turn the ceiling fan on, it is due to the magnetic effect of current. Let us learn more about the heating and magnetic effects of electric current.
What is the effect of electric current in electric fan?
Example: When an electric current is supplied to an electric fan, its blades start moving. Along with moving of blades of fan, motor of electric fan gets warmed also. If electric current is supplied to an electric circuit with resistor only, the electric current is consumed in raising the heat of the resistor.
How does a ceiling fan work electrically?
The ceiling fan has a motor that converts electrical energy into mechanical energy. … As the electrical current reaches the motor, it enters coils of wire that are wrapped around a metal base. When this current passes through the wire, it creates a magnetic field which further exerts force in a clockwise motion.
What makes the electric fan move?
Electric fans have a motor that moves blades that are attached to a central rotating hub. … Electric fans have a motor that turns a shaft on which there is an impeller. The turning impeller creates air pressure, causing air flow. If the fan moves air in the same direction as its shaft, it is axial flow.
Which are the effects of electric current?
Hence, the three effects of electric current are heating effect, magnetic effect and chemical effect.
Which effect of current is used in electric light bulb?
The heating effect of current is utilised in an electric bulb.
What energy transformation takes place in electric fan?
The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.)
Why capacitor is used in fan?
The capacitor is used not only to start the fan but also to make it spin. In simple words, the capacitor creates a magnetic flux (torque) which makes the fan rotate. Generally, two capacitors in parallel series are used in the ceiling fan. … In other words, a fan will have a single-phase induction motor in it.
Does electric fan work on electromagnetic induction?
The electric fan works on the principle of electromagnetic induction; the electric fan works by the use of the electric motor. The coil of wires wounded on the metallic core is attached with the electric motor, and then in this arrangement of the wires, the current is passed.
What makes a ceiling fan effective?
Ceiling fans are considered the most effective of these types of fans, because they effectively circulate the air in a room to create a draft throughout the room. … If you use air conditioning to cool your home, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.
What is the principle of electric fan?
Electric fan works on the principle of conversion of electric energy into mechanical energy by means of magnetic fields and in this case converted mechanical energy is consumed as rotary motion of fan blades.
What is the benefits of electric fan?
A key advantage of electric fans is increased engine cooling and improved air conditioning cooling at idle, when it is most needed. In addition, replacing an engine-driven fan can increase horsepower and improve fuel economy as the engine drag from turning the fan is eliminated.
How is electromagnetism applied in electric fan?
The motor contains an electromagnet that is connected to a shaft. When current flows through the motor, the electromagnet rotates, causing the shaft to rotate as well. The rotating shaft moves other parts of the device. For example, in an electric fan, the rotating shaft turns the blades of the fan.
