Electric arc welding is a type of welding that uses a welding power supply to create an electric arc between a metal stick, called electrode, and the workpiece to melt the metals at the point of contact. So, by relative motion between a coil and a magnet, we are changing the magnetic flux associated with the coil which in turn induces emf in the coil. The electric arc welding gives superior temperature at the point of welding. When the armature is rotated anticlockwise, the left arm of the armature will move inwards, and the right arm of the armature will move outwards. So it has far superior arc quenching properties than any other medium (oil in oil CB, SF6 in SF6 circuit breaker). The working principle of these motor was depending on Coulombs law. The 3-phase revolving-armature generator. Once this turbine is connected to the electrical generator then kinetic energy (K.E) of the vapor drives in opposition to the fan-type blades in the turbine, thus the rotor in the electrical generator will rotate and generate electricity. A When the coil is at 360 degrees, the coil has completed one rotation and it moves parallel to the magnetic field and induces zero emf. increasing the strength of the magnetic field. Since it can interrupts a current in a vacuum without producing any special harmful gas to the environment, and it is also consisted of an ordinal ceramic or glass, and metallic components, a vacuum circuit breaker is considered a more desirable circuit breaker than SF6 one. An outer frame encloses both the stationary and rotating part. Working principle and types of an Induction motor; Transformer losses and efficiency; Difference between synchronous motor and induction motor; Characteristics of DC motors; Speed control methods of DC motor Thus, in \(DC\) generator the induced current does not change its direction and hence is not alternating in nature rather it is direct in nature.
