maximum or peak value
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.
This is often called a "voltage drop".
It's alternating current
That's called a transformer.
That's called a transformer.
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.
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.
Is called AC voltage or current.
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.
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
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.
Although in AC, the voltage does change, it is the reversing of direction of flow of the current which was used to designate the AC name.AnswerIn engineering terminology, the abbreviation a.c. is considered to be an adjective. So, it is 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. However, it is also correct to use the term 'alterating voltage', where applicable.
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
The highest point reached by any body in the sky, including the Sun, is called the zenith.
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.
