Questions & Answers

The real Ramsay Electrical Test is timed and scored. However, you can choose to answer our sample test at your leisure if you'd like, to give yourself a general idea of your own preparedness. Alternatively, you can simulate the conditions of the real exam by setting a timer and checking your score when you finish.

  • Question #2

What is the binary value of the hexadecimal number 0xA2?

10100010b
10101010b
10110001b
None of the above
Correct Answer
Incorrect Answer

The correct answer is A.

A hexadecimal number has a base of 16 numbers starting from 0 to 9 and then A to F. Any number with “0x” before represents a hexadecimal number, and “b” after the number represents a binary number. Each hexadecimal number is represented by four binary bits. Since there are 2 hexadecimal numbers, the resultant binary of the given number will be 8 binary bits. Follow the figure provided below:

Where should a voltmeter be connected to when checking the fuse only?

Between A and G
Between B and G
Between C and G
None of the above
Correct Answer
Incorrect Answer

The correct answer is C.

The symbol of the fuse is shown in the figure below. There is a 10A fuse in the circuit, and it is used to protect the circuit. If the cooling fan tries to draw more than 10A, the fuse will blow and the circuit will stop working. In order to check the fuse, the voltmeter should be placed between C and G as shown in the figure below.

  • Question #4

A full-wave rectifier is subjected to a 50 Hz AC voltage. What is the frequency of the output voltage?

50
100
150
None of the above
Correct Answer
Incorrect Answer

The correct answer is B.

A full-wave rectifier circuit is shown in the figure below. The input AC voltage is applied to the transformer and the rectified output is shown as well. It can be seen that the negative cycle of the input is flipped to the positive side, which is called rectification. Since the output of a full-wave is twice the input frequency, therefore, B is the correct choice.

  • Question #5

Use the following PLC program to answer the question below:

 

Ramsay Electrical Sample Test

 

Identify the statement which is NOT true for this program:

X2 is open in case of excessive vibrations
X3 is open in case of overload
X4 is open when hot
X2 os closed in case of normal vibrations
Correct Answer
Incorrect Answer

The correct answer is C.

This PLC program is starting/stopping the electric motor as well as setting trip conditions in case of excessive vibrations, overcurrent (overload), and high winding temperatures. X2 is the vibration contact and it is closed when there are no vibrations and vice versa. Since it is a correct statement, A as well as D cannot be the correct choice. X3 is the overcurrent monitor contact and is open in case of overload. Therefore, B cannot be the correct choice since it is also correct for the program. X4 is closed when hot and open when it is okay. Therefore, C is the correct choice as this is a wrong statement.

  • Question #6

In a 110V electrical system, there are three appliances: appliance A (550W) appliance B (770W) and appliance C (330W). Given that all appliances operate simultaneously, what is the minimal required fuse rating?

15A
20A
25A
30A
Correct Answer
Incorrect Answer

The correct answer is B.

The minimal fuse rating should be higher than the normal operating current of the system. Since an electrical system is connected in parallel, the total current in the system when all three appliances are working is the sum of all three.
The current consumption of each appliance is calculated by:

Ramsay Electrical Sample Test

Where:
P = Power [Watt]
V = Voltage [Volt]

Therefore, appliance A consumes 550/110 = 5A
Appliance B consumes 770/110 = 7A
Appliance C consumes 330/110 = 3A

The total current in the system is 5 + 7 + 3 = 15A
In order to withstand normal working conditions, the minimal fuse amperage rating must be greater than 15A, thus 20A.


  • Question #7

Which tap contains a smaller number of threads at the chamfer region of the tap?

Plug tap
Taper tap
Bottoming tap
None of the above
Correct Answer
Incorrect Answer

The correct answer is B.

Taps are used to create threads in a workpiece. There are three main types of taps: taper tap, plus tap, and the bottoming tap as shown in the figure below. The main difference between these types is the number of threads in the chamfer region as shown. The taper tap contains the least number of teeth and is generally used at the beginning of the threading process. The plug tap contains more teeth than the taper tap and is used for repairing a threaded hole. Whereas the bottoming tap contains an almost uniform number of teeth throughout the length of the tap and is used to tap the bottom of the hole generally. Bottoming tap is the last tap to be used in the tapping process. Since taper tap contains the least number of teeth at the chamfer edge, choices A, C, and D cannot be true, and B is the correct choice.

  • Question #8

Which electronic device you will select to switch on and off a load containing a higher magnitude of current?

electromechanical relay
Solid-state relate
Mechanical switch
None of the above
Correct Answer
Incorrect Answer

The correct answer is B.

Switches/relays, when used to switch higher current, produces sparks on the contact terminals. It is not advised to use electromechanical relays since the contacts are made mechanically, and sparks are produced. Therefore, A cannot be correct. Solid-state relays (SSR) are electrical switches made up of semiconductors, especially for higher loads. Since there is no mechanical motion, the sparks are not generated on the contact terminals. Therefore, B is the correct choice. A mechanical switch is not an electronic device, and it produces sparks as well. Thus, C cannot be correct as well.


  • Question #9

Use the following diagram to answer the question below:

 

Ramsay Electrical Sample Test

 

With all conveyors running, what happens if OL1 opens?

Only conveyor 1 will stop
Only conveyor 2 will stop
Conveyors 2 and 3 will stop
None of the above
Correct Answer
Incorrect Answer

The correct answer is A.

From rung 1, if OL1 opens, this implies conveyor motor M1 will stop and the normally open (NO) contact M1 becomes 0. Since conveyor motor 2, as well as 3, are not dependent on M1 NO as seen in rung 2 and 3, these motors will keep running. Therefore, A is the correct choice. See the figure below to understand the logic flow:

  • Question #10

Interchanging two of three terminals in a motor will cause it to:

Stall
Maintain constant speed
Reverse rotation
Shore circuit
Correct Answer
Incorrect Answer

The correct answer is C.

When interchanging two of the three terminals of a motor, it will reverse its rotation direction. That is exactly how a forward reverse starter works.
