Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers are of two types - step-up and step-down transformers
The basic principle of transformer working is electromagnetic induction
The transformer consists of two coils - primary and secondary
When an alternating current flows through the primary coil, it creates a magnetic field which induces a v...
An induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
Consists of a stator and a rotor
Stator has a set of coils that produce a rotating magnetic field
Rotor is made up of conductive bars and is placed inside the stator
The rotating magnetic field induces a current in the rotor, which in turn produces a magnetic field
The interaction between the two magne...

Survey in R.E. refers to the process of collecting data and information about a specific area or site.
Survey in R.E. involves measuring and mapping the land, identifying boundaries, and assessing topography.
It helps in understanding the existing conditions of the site and is crucial for planning and designing construction projects.
Survey techniques include using GPS, total stations, and other instruments to gather accu...
Sag is the vertical distance between a conductor's position when it is in tension and its position when it is in a relaxed state.
Sag is caused by the weight of the conductor and environmental factors such as temperature and wind.
To minimize sag, conductors can be made of materials with higher tensile strength, or additional support structures like suspension insulators can be used.
Sag can also be minimized by increasin...
Billing for a 1 km line involves calculating the cost based on the length of the line and any additional factors.
Determine the cost per unit length of the line
Multiply the cost per unit length by the length of the line to calculate the total billing amount
Consider any additional factors that may affect the billing, such as taxes or fees
Provide a detailed breakdown of the billing to the client, including the cost per un

Surge arrestors protect electrical equipment from voltage spikes and surges.
Surge arrestors are devices that limit the voltage supplied to electrical equipment during a surge or spike.
They protect equipment from damage caused by overvoltage.
Surge arrestors are commonly used in power distribution systems, telecommunications networks, and electronic equipment.
They work by diverting excess voltage to the ground, preventin...
