🔍 Key Concepts

• Synchronous speed formula for AC machines • Relationship between frequency, number of poles, and speed • Unit consistency: Hz (cycles per second) vs rpm (revolutions per minute)

💭 Think About

• What is the standard formula that relates synchronous speed to system frequency and number of poles? • If you plug 20 Hz and 24 poles into that formula, what numerical value do you get before converting units, if needed? • Are you correctly handling the conversion from revolutions per second to revolutions per minute?

✅ Before You Answer

• Write the exact formula and substitute 20 Hz and 24 poles carefully. • Make sure you multiply by 60 at the correct step when converting to rpm. • Compare your final result to the options and check if it matches exactly one of them.
