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