Time taken by AC to reach half of maximum value is........ While initial phase of A. C is 90degrees |
| Answer» ES in an AC sine WAVE, means that the system is operating with a supply that has a frequency of 60hz = 60 cycles per second. Therefore, the cycle time for such a system is 1/60 seconds (16.67 ms). Each cycle COMPRISES, one positive GOING voltage duration and one negative going voltage duration. | |
