Question 1
The formula used for power in watts delivered to a three-phase balanced resistive load is:
◦
3 × E phase× I Line.
◦
1.73 × E phase× I phase.
◦
3 × E line× I line.
◦
1.73 × E line× I line.
Question 2
The generator principle is based on the fact that:
◦
voltage is induced in a conductor whenever it is placed in a magnetic field.
◦
voltage can be induced in a conductor when it is moved so as to cut magnetic lines of force.
◦
rotating a conductor can generate electricity.
◦
voltage is induced in a conductor when it is moved in a parallel direction with the magnetic lines of force.
