1.
An alternator is an electromechanical ac generator.

2.
Compare the total copper cross sections in terms of current-carrying capacity for a single-phase and a three-phase 120 V system with effective load resistance of 15 Ω.

3.
In a Y-connected circuit, between each line voltage and the nearest phase voltage, there is a phase angle of

4.
The stator is the rotating assembly in a generator or motor.

5.
In a Y-connected source feeding a ∆-connected load,

6.
A three-phase generator is connected to three 90 Ω load resistors. Each coil generates 120 V ac. A common neutral line exists. How much current flows through the common neutral line?

7.
A two-phase generator is connected to two 90 Ω load resistors. Each coil generates 120 V ac. A common neutral line exists. How much current flows through the common neutral line?

8.
Power is measured in a three-phase load by using an ammeter.

9.
In a Y-connected generator, there is a 120° difference between each line voltage and the nearest phase voltage.

10.
In a ∆-connected generator, there is a 120° difference between each line current and the nearest phase current.
