FAQs - Contracting

A socket is fastened to machinery or a building's structure and connected to an active electrical circuit. A plug is the movable connector coupled to an electrically operated device. A male connector, the plug frequently has projecting pins that fit over the holes and female contacts in a socket.

A switch that, in the event that the machine is opened, turns off electricity to certain components (such as motors and lamps). This is to protect people from harm if they accidentally try to open the machine. Otherwise, known as a "safety switch."

A cabinet or box that shields electrical or electronic equipment and guards against electric shock is known as an electrical enclosure. Typically, enclosures are built of stiff polymers or metals like aluminium, steel, or stainless steel.

A wire is a single conductor, but a cable is a collection of conductors, and this is the fundamental distinction between wires and cables. Nevertheless, the copper or aluminium used to make these conductors is a common material. The cables are typically bare and twisted. However, some of the cables have a thin PVC covering applied to them.

An ohmmeter can be used to directly measure the resistance of the windings.

The winding that receives the DC excitation current is the synchronous generator's field. The winding that the load is attached to is the armature. Small generators frequently have the armature windings on the rotor and the field windings on the stator.

Copper or aluminium is used to make armature wiring. Due to its greater electrical conductivity, copper armature wiring improves electrical efficiency.

The ratio of the induced EMF per coil when the winding is short-pitched to the induced EMF per coil when the winding is full-pitched is known as the pitch factor.
