Across
  1. 2. used extensively in computer circuit
  2. 9. refers to how rapidly the current reverses or how often the voltage changes polarity
  3. 10. the time to complete one cycle
  4. 12. periodically changes the direction in which it is flowing.
  5. 13. a common three phase wire with three hot wires and a neutral wire
  6. 14. also called the minimum value of the negative and of the positive half-cycle are equal
  7. 15. the base unit of frequency
  8. 16. common centered connection of the phase windings
  9. 18. the most common type of AC waveform
  10. 20. a function of the amount of flux cut by the conductor per unit of time
  11. 23. magnitude changes continuously
  12. 25. part of a waveform that does not repeat or duplicate
  13. 28. these are the same as phase voltages
  14. 30. periodically reduces to zero
  15. 31. the effective value of the alternating current is that value that produces the same heat in a resistive circuit as a direct current of the same value
  16. 32. alternating current could be conf=verted to direct current
Down
  1. 1. the type of of current produced in an amplifying resistor
  2. 3. when the motion is 90 degrees to the flux
  3. 4. the voltage's value at a specific moment in time
  4. 5. the number of electrical degrees equals to this
  5. 6. for all three phase voltages is the center of Y
  6. 7. used in in television receivers, radar receivers, and other electronic devices
  7. 8. converts AC to pulsating DC by allowing only one half-cycle of the AC waveform to pass through a diode, blocking the other half
  8. 11. the standard electrical potential in buildings
  9. 12. could be specified in many different ways
  10. 17. electrically connected to ground
  11. 19. represented by a line on the graph
  12. 21. degrees that marks off the horizontal acts of a waveform
  13. 22. a popular device used to rectify AC
  14. 24. half cycle waveform
  15. 26. ideal for stable power distribution
  16. 27. power produced by alternating current and alternating voltage
  17. 29. these are not equal to phase currents
