Question 1

An arrow through (or to) a symbol changes the component from a variable value device to a fixed value device.

Accepted Answer

An arrow through or to a symbol typically indicates that the component is adjustable or variable, not fixed.

Question 2

Surface mounted devices commonly take up to three times the space of feed through printed circuits.

Accepted Answer

Surface mounted devices (SMDs) are designed to take up less space on a printed circuit board (PCB) compared to through-hole components, allowing for more compact and efficient designs.

Question 3

According to ASME, the key to effective communication on electrical drawings is the use of standardized symbols so that anyone who uses the diagram makes the same interpretation.

Accepted Answer

ASME recommends the use of standardized symbols on electrical drawings to ensure that everyone who uses the diagram can interpret it in the same way. This helps to avoid confusion or errors that may result from different interpretations of the symbols.

Question 4

A coil is a conductor wound on a form or in a spiral that has inductive properties.

Accepted Answer

This statement is true. A coil's inductive properties come from the magnetic field generated as current passes through the wound conductor.

Question 5

All electronic component values are extremely large (2,500,000,000,000).

Accepted Answer

This statement cannot be true as electronic component values can range from picofarads (10^-12) to farads and from ohms to megaohms, depending on the type of component. A value of 2,500,000,000,000 would be very large for certain components, but not all.

Question 6

The designating system has developed around a letter indicating the type of component followed by a number that gives the sequence of the part in the circuit.

Accepted Answer

This is a correct description of the designating system for electronic components.

Question 7

The printed circuit board assembly drawing is a complete engineering drawing, including components, assembly and fastening or soldering specifications, and a parts list or bill of materials.

Accepted Answer

The answer of The printed circuit board assembly drawing is...

Question 8

The circuit board artwork can have a separate sheet called silk screen artwork containing component outlines and orientation symbols.

Accepted Answer

Silk screen artwork is a separate layer that contains component outlines and orientation symbols on a circuit board artwork.

Question 9

According to ASME, there should be no variation to electrical symbols or electronic symbols because of the possibility for misinterpretation.

Accepted Answer

ASME allows for some variation in electrical and electronic symbols to accommodate different design needs, as long as the symbols remain clear and unambiguous.

Question 10

Schematic diagram is used to show the relationship of the components and equipment located in the substation.

Accepted Answer

A schematic diagram is a type of diagram that shows the relationship between the components and equipment located in a substation or any other system. It usually includes symbols that represent each component and lines that connect them to show how they are connected or linked.

Question 11

A 34000 ohm resistor is the same as a 3.4k ohm resistor.

Accepted Answer

A 34,000 ohm resistor is equivalent to a 34k ohm resistor, not 3.4k ohm.

Question 12

The uniformity of symbols within a print is not critical to the final layout.

Accepted Answer

The uniformity of symbols within a print is crucial for maintaining consistency and coherence in the final layout. It helps in creating a cohesive visual appeal and prevents confusion for the intended audience.

Question 13

Electrical diagrams are generally drawn to scale.

Accepted Answer

Electrical diagrams are typically not drawn to scale; instead, they use symbols to represent components and lines to represent connections, focusing on how the circuit functions rather than the physical layout.

Question 14

An electrical system is the same thing as an electrical circuit.

Accepted Answer

An electrical system refers to a broader network or infrastructure that consists of multiple electrical circuits. An electrical circuit, on the other hand, refers to a closed loop of electrical components and wires that allow the flow of electric charge. Therefore, an electrical system may contain multiple electrical circuits, but not all electrical circuits make up a complete electrical system.

Question 15

The only drilled holes that are required when using surface mounted devices are the ones for chassis mounting or feed through between layers.

Accepted Answer

Surface Mounted Devices (SMDs) are soldered directly onto the surface of printed circuit boards (PCBs), eliminating the need for through-hole drilling except for chassis mounting or creating electrical connections between different layers of the board.

Question 16

Electrical circuits provide the path for electrical flow from the source of electricity through system components and connections and back to the source.

Accepted Answer

Electrical circuits do indeed provide the path for electrical flow from the source of electricity through system components and connections and back to the source.

Question 17

The placement of identification numbers of electronic components is variable.

Accepted Answer

The answer of The placement of identification numbers of electronic...

Question 18

Schematic diagrams drawn as a series of lines and symbols that represent the electrical current path and the components of the circuit. Provides the basic circuit connection information for electronic products.

Accepted Answer

Schematic diagrams are indeed drawn as a series of lines and symbols representing the electrical current path and components, providing basic circuit connection information for electronic products.

Question 19

Printed circuit boards do not need to have separate mounting holes for each component lead or terminal.

Accepted Answer

Printed circuit boards typically have designated pads or areas for components to be soldered onto, but separate mounting holes for each lead or terminal are not necessary.

Question 20

There are separate terminal pads for each component lead or wire attachment on printed circuit boards.

Accepted Answer

This statement is true. Separate terminal pads are provided for each component lead or wire attachment on printed circuit boards.
