Prepare and exhibit posters showing the need for conserving electrical energy.

The figure of a star connection is shown below. Observe the figure and correct mistakes, if any, and answer the questions:

(a) Each end of the secondary coils coming out of a distribution transformer is connected to a common point. What is the name given to the line that starts from here?

(b) Which pairs of lines are used in household electrical wiring? What will be the voltage between them?

(c) What is the voltage between two phase lines?

Using the information given in the brackets, complete the flow chart. (rotor, coil wound over the soft iron core, electromagnet, stator)

Exhibit a model of electrical distribution network.

Draw an electrical circuit containing the electrical appliances required for your class room.
