🔍 Key Concepts

• Frequency in electrical systems (measured in hertz, Hz) and what it physically represents • The relationship between rotational speed (RPM) and how many electrical cycles are produced per revolution • How construction features of an alternator affect how many cycles are produced each revolution

💭 Think About

• When the rotor makes one full mechanical revolution, what inside the alternator determines how many complete AC cycles are produced? • Which feature of the alternator will directly change how many times the magnetic field passes a given point each revolution? • If you kept the RPM the same but changed only one design feature of the alternator, which option would clearly change the output frequency?

✅ Before You Answer

• Be clear on what frequency (Hz) means: cycles per second, not voltage level or current strength • Distinguish between things that affect magnitude (how big the voltage is) vs. things that affect rate of change (how often a cycle repeats) • Focus on which choice changes how many times the magnetic field cuts the armature conductors during one mechanical revolution at a fixed RPM
