How match 2 phase line voltage between them?
To match 2 phase line voltage it has to be the same voltage.
What would be the best way to wire lights in a house in series or in a parallel give 2 advantages of the method?
1.) In series if 1 light bulb goes out they all do.2.) For each appliance to operate at its rated power, it must be subject to its rated voltage which corresponds to the value of the supply voltage. A parallel connection ensures that each branch is subject to the same (supply) voltage.
What are the diff types of rectifier?
The various types of rectifiers are :1: half wave rectifier2: full wave rectifier3:bridge rectifiersthe rms voltage of half wave rectifier is v/sqrt(2)t
What does it mean to say that current and voltage in a circuit are directly related?
It means that when one increases, the other increases as well. Also, it implies that this increase is proportional - if the voltage is doubled, the current will also double. Note 1: Normally, the voltage is considered the independent quantity; that's the quantity you can control directly. And if the voltage changes, so will the current. Note 2: In simple circuits, such as those that only have a voltage source and resistors, the relation will be a direct proportion. With electronic components, such as a transistor, the relationships can be more complicated.
Name the three basic methods that are used to vary the speed of a DC motor?
speed of a dc motor can be varied by mainly two methods:- 1)field control method 2)armature control method further , field control method can be divided in 3 parts:- 1)field rhestat control method---speed variation is acomplished by means of a variable resistance inserted in series with shunt field 2)reluctance control method---by changing the reluctance of magnetic circuit by choosing right material.. 3) field voltage control method-requires variable field voltage supply. and armature control method can be divided in 3 parts :- 1)armature resistance control---variable resisitance connected in series with armature 2)shunted armature control. 3)armature voltage control. ------------mrityunjay pandey (kiit university ,btech 2nd year)
What is low voltage release?
A low voltage release is provided by a 2-wire control circuit. In the event of a power failure, the magnetic motor starter will drop out.
What are the 2 advantages of 24 Volt current?
Low voltage circuits are any circuits under 30 volts, usually 24 volts. 24 volt circuits are usually control circuits. The amount of current in these systems is usually small, under 5 amps. Since the voltage and amperage is very low, wiring can be much smaller and therefore much cheaper to install than "line" voltage wiring. Low voltage is also much safer.
What are the advantages of business alliance for small company?
1.to sell good at particular time.2.no more expire.
Advantages of SMPS over linear power supply?
1.Efficiency is high compared to linear power suplies 2.ripple voltage is very low 20mv. 3.constant regulating voltage is the one of the advantage of smps.
In what two ways can the speed of a dc motor be varied?

Give 2 advantages of using windows encvironment compared with a command line environment?
1) A windowed environment or Graphical User Interface (GUI) is much easier to use. It allows people who are unfamiliar with computers or a particular program to quickly figure out how to use the program. 2) Depending on the skill level of a user, the user might make fewer mistakes if they use a GUI. However, there are advantages to the command line including: 1) Speed - command line programs tend to be smaller and run faster. 2) Control - the command line gives the user must more control than a GUI.
What are advantages of a dictatorship?
1. Decisions are made and carried out very fast 2. There is strict order and control of the population (this can also be a disadvantage at times)
How do you reduce induced voltage in control cables?
You can reduce induced voltage in control cable by applying the following methods. 1. While laying control cable keep a minimum distance 300mm from the power cable. 2. If possible try to lay control cable on the separate cable tray. 3. Earth the Armour/ screen of the control cable on both side of the cable or at-least at one side. Some times it is not important to reduce the the induced voltage in control cable, but it's effect on relay or contactor as the contactor or relay does not pick-down even after the removal of the control supply. In that case it is recommended to use two relay/contactor in parallel and use the contacts in series or parallel for control circuit interlocking.
What are the negatives about series circuits?
1) If any component fails, then the whole circuit fails. 2) Voltage across any component may be hard to control.
How many Methods can be use to control the speed of Single Phase Induction Motor?
