What else can I help you with?
Is a device that changes the voltage of an alternating current with little loss of energy?
The device you are referring to is called a transformer. Not only can a transformer increase voltage, it can decrease voltage as well. These are known as a step up transformer for increasing voltages and step down for decreasing voltages.
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
The kind of electricity from the power plant is called?
There are only two kinds of electricity, direct current and alternating current. All power plants now produce alternating current
The incoming voltage from the current source to the transformer is called what?
The incoming voltage from the source to the transformer is called primary voltage.
What is the set up for a transformer that decreases the voltage on the out put side?
A basic, two-winding, transformer consists of two, separate, coils (called windings) wound around a laminated silicon-steel core. The winding connected to the supply (input) is called the primary winding, and the winding supplying the load is called the secondary winding. Alternating current flowing in the primary winding sets up an alternating magnetic field in the core which induces a voltage into the secondary winding. If there are fewer turns in the secondary winding, then the secondary voltage is lower than the primary voltage. If there are more turns in the secondary winding, then the secondary voltage is higher than the primary voltage.
A device that increase the voltage of an alternating current is called a?
That's called a transformer.
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 it is called alternating current not alternating voltage?
There's absolutely nothing wrong with using the term 'alternating voltage', if you are describing voltage rather than current. However, In engineering terminology, the abbreviation a.c. is considered to be an adjective. 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 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
Can alternating current be expressed as a vector?
In the case of AC, you can express the current, the voltage and the equivalent to the resistance (called "impedance" in this case) as a vector - with a magnitude, and a phase angle.
What is an opposition to current flow called that occurs in an alternating current circuit?
The resistance is called impedance, and is equal to the measured voltage divided by the measured current, through Ohm's Law (V = ZI, Z = V/I).
What do you call a current that changes directions at a regular rate?
"alternating"
Current in which electrons flow in the same direction is called?
It's alternating current
What is the current called when electrons reverse regularly?
Alternating current aka AC.
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
Changing alternating current to direct current is called?
Rectification
