electrical circuits.
What are transformers used for? And explain the process. - ANSWER They are used to
increase or decrease the voltage in electrical circuits. First lower the current passing through
transmission lines by increasing the voltage and then decreasing the voltage coming to the
city, into homes and factories.
What are the components of a transformer? - ANSWER Iron Core, Windings, Bushings,
Radiators, Temperature Sensors, Oil gauge.
What is a Step-Up Transformer? - ANSWER It increase the voltage and decrease the
current. It is used to reduce the line losses. By increasing the voltage, the line current
proportionally decreases and power loss from cable resistance is reduced.
What is a Step-Down Transformer? - ANSWER It decreases the voltage to go into homes
and increases the current.
Where does a Step-Up Transformer have more coil? - ANSWER The secondary coil
Where does a Step-Down Transformer have more coil? - ANSWER The primary coil
What are some applications of a Step-Down Transformer? - ANSWER Adapters, cell
phone chargers, transmission lines, welding machines, TVs, inverters
