What is called an effective voltage in Alternating current and if you mention 115 V ac 3 phase means peak voltage is 115 or it is an effective voltage?
Selvame
115 is the RMS voltage. The actual voltage is a sine wave from -167 to +167 relative to ground. RMS stands for root-mean-square, and it a way of saying that 155 Volts of DC would do the same work on the same sized load.
There can be up to 3 phases, and they are the sine wave, shifted by a part of the curve. In most houses, there are 2 phases, and the voltage to ground for each is 110 to 120 V RMS. The voltage between the 2 is 230-240VRMS.
3 phase gets very complex. Each phase is 115 to ground or neutral. 3 PHASE 115V AC EACH PHASE IS 120 DEGRES PHASE SHIFTED THE EFFECTIVE VALUE IS .639 X 115 THE PEAK VALUE OF PHASE IS 1.41X RMS VALUE.

Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
What is the voltage rating for 240VAC?
240 volts alternating current (240vac)
Why you say AC as alternating current not alternating voltage?
Because its the current that is alternatingAnother AnswerThere's absolutely nothing wrong with using the term 'alternating voltage', if you are describing voltage rather than current. However, In engineering terminology, the abbreviationa.c.is considered to be anadjective. So, it is also quite normal to talk about an 'a.c. voltage', in just the same way as we describe an 'a.c. system', or an 'a.c. motor', etc.
What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

What type of device is used to increase or decrease the voltage of an electric current-?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
Why is alternating current more effective at long distance travel than direct current?
Transformers increase and decrease voltage as needed. PLATO
What is alternating current normally produced by?
Alternating current is normally produced by rotating the magnet in the coil of an induced alternating voltage. When connected to a circuit, an alternating current will flow.
What is the voltage of alternating current?
60 Hz
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
What are the uses of alternating current?
voltage can carry current a further distance.
What are the kinds of voltage?
Alternating current - AC, and direct current - DC.
When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
A transformer can only the voltage of an alternating current?
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
Why do electric company generators produce alternating current?
Because alternating current can be run through a transformer to step up or down the voltage. High voltage current incurs lower losses in transmission.
A devise that increases or decreases the voltage of alternating current?
TRANSFORMER
