If alternating current is impressed on one coil what will be the frequency of the induced voltage in another coil with which it is coupled?
Same frequency as that of primary coil
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.
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.
What is the meaning of DC Voltage?
D.C. stands for direct current. A.C. is alternating current.
What is the frequency of the alternating voltage and current typically used in the US?
60 Hertz
If alternating current is impressed on one coil what will be the frequency of the induced voltage in another coil with which it is coupled?
Same frequency as that of primary coil
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.
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 is a frequency of ac signal in Pakistan?
The current which changes it direction after every half cycle is called alternating current(A.C) or Alternating current which produced by voltage source whose polarity keeps on reversing with time. By Shahnam qadeer
What type of current is used in your home alternating or direct?
In North America the electrical system is alternating current at a frequency of 60 Hertz. Europe and the UK use alternating current at a frequency of 50 Hertz. Direct current systems are obsolete because of the inability to transmit the voltage over long distances.
Frequency depends on voltage or current?
Frequency doesn't depend on either voltage or current.
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
Moving a magnet in and out of a coil of wire produces?
That will induce a voltage across the wire.
What is ac and DC supplies?
AC supply means the supply voltage is alternating one. Supply has some particular frequency and magnitude. e.g. usual power supply to domestic use DC supply means the supply voltage (or current) is not alternating. It is fixed one. i.e. frequency is zero. e.g. batteries
How does the frequency of a changing magnetic field compare with the frequency of the alternating voltage that is induced?
A changing magnetic field generates an electric field and alternating currents are accompanied (or caused) by alternating voltages.
