How does time relate to degrees in an AC sine wave?
One cycle of the sine wave is equal to 360 degrees. In US the frequency of power is typically 60 Hz and hence one cycle is 1/60 of a second. Therefore you can calculate the degrees at any instant of time. If at zero degrees the voltage amplitude is zero, then at 90 degrees,which is 1/4 cycle, wave is at peak voltage. At 180 degrees it is at 1/2 cycle and zero voltage and then at 270 degrees it is 3/4 of the cycle and a peak negative voltage. Finally at 360 degrees the cycle is complete and the voltage is again zero.
Why power is measured in terms of kva not in kw in ac supply?
Unlike DC in AC Power is the Product of Voltage*Current*Power FactorP = V*I*PFIn the above expression power factor is a variable quantity which can be different for different circuit hance does not allow you to specify ratings in KW rather then KVA.
What is electrical degree?
An 'electrical degree' is 1/360th of one complete cycle of AC. This does not necessarily coincide with a 'mechanical degree', as it depends upon the design of the generator that produces the AC voltage. For a two-pole machine, the armature (rotating winding) must rotate 360 mechanical degrees in order to generate one complete cycle or 360 electrical degrees. A four-pole machine's armature, on the other hand, need only rotate through 180 mechanical degrees to generate one complete cycle or 360 electrical degrees.On the other hand, you could be asking about a bachelor's degree in electrical engineering?!
The period of an ac wave is?
period is the time duration of one cycle of the waveform, and is measured in seconds/cycle. AC power at 50 Hz will have a period of 1/50 = 0.02 seconds/cycle. A 60 Hz power system has a period of 1/60 = 0.016667 seconds/cycle
What is ac waveform?
AC waveform is a graph that tells the degree and radiant. On the graph the degrees is graphed in top and the radiant is on bottom.
How many times current becomes zero in one ac cycle?
3 times, at 0,180 & 360 degrees Is it not twice? (two times?) The third 360 degrees is the start of the next cycle? or the first 0 degrees was the end of the previous cycle?

What does AC stand for in terms of electricity?
AC stands for Alternating Current in terms of electricity.
What does AC mean in history terms?
Un-sure of AC in terms "AFTER CHRIST" is a common one
Why does ac compressor cycle on and off when heat is on in a 98 ford explorer?
If you have the heat on in the defrost position , the air conditioning compressor will cycle on and off to help dehumidify the air if the outside temperature is about 50 degrees Fahrenheit or warmer
How does DC differs from AC?
The AC current oscillates with cycle time to time.
What does 10 degrees celcius in ac?
10 degrees Celsius is approximately 50 degrees Fahrenheit.
What do you need to convert your razor from 60 cycle ac to 50 cycle ac?
A: There are devices transformers that can safely convert power the reason being that a 50 cycle the razor will saturate causing heating and blow.

Can diode work on ac power supply?
diodes conduct electricity in only one direction but as ac change direction in each of its cycle diodes can only conduct half of its cycle which will give u a pulsating dc. but if dc is mixed with ac and if it can put whole of its cycle in positive direction diode can conduct ac. so diodes are usually used to produce dc from ac.
Why does your ac unit not cycle off and on?
Bad compressor
