Question

QUESTION 1 Which of the following is the largest combination of interconnected things? System Unit Module Component QUESTION 2 Which one of the troubleshooting methods normally follows a signal from input to output? Half Testing Injection Tracing Shotgun

Answer 1

1 Ans- System

system is the largest combination of interconnected things .

Unit is an individual thing or person

Module- a standard or unit

Component- single thing

2.Ans- Half testing

It is the troubleshooting method normally follows a signal from input to output

The HALF-SPLIT technique is extremely powerful in locating faults in medical devices created of an outsized variety of blocks asynchronous. deem example AN X-Ray unit. Since there are unit several blocks it's attainable to divide the circuit in half, take a look at that half, decide that half is functioning then split the non-functioning section into half once more to find the fault.

3. Ans -​​​​​​-Contacts

A relay has two major section coil and contacts

Two major section contain the energizing circuit and therefore the contact circuit. The coil is on the energizing aspect; and therefore the relays contacts area unit on the contact side. once a relays coil is energized, current flow through the coil creates a force field

4.Ans -​​​​​--Commutator

Movement of the force field is achieved by shift current between coils at intervals the motor. This action is termed "commutation". terribly several DC motors (brush-type) have constitutional commutation, that means that because the motor rotates, mechanical brushes mechanically change by reversal coils on the rotor.

5.Ans.- same

In series dc motor the field winding is in series connection with armature , so same current is pass through both armature and field winding

6.Ans-​ Overload

The contactor applies voltage to a contactor coil to shut the contacts and to produce and interrupt power to the circuit. A motor starter is just a contactor and AN overload relay and is rated by motor horsepower or electrical phenomenon. If there's no overload relay it's not a starter any further. It's back to being simply a contactor.
