In which type of circuit, each load can be turned on or off independently from the others
-
Series
-
Complete
-
Parallel
-
Grounded
Correct Answer
A. ParallelExplanation
In a parallel circuit, each load is connected to the same voltage source but has its own separate path for current flow. This means that each load can be turned on or off independently from the others without affecting the operation of the other loads. In series circuits, turning off one load would interrupt the flow of current to all the other loads. Therefore, the correct answer is parallel.Rate this question:

A circuit in which the total circuit current flows from one load to the next is called a _______ circuit.
-
Series
-
Complete
-
Parallel
-
Grounded
Correct Answer
A. SeriesExplanation
A circuit in which the total circuit current flows from one load to the next is called a series circuit. In a series circuit, the components are connected in a chain, so the current passes through each component one after the other. This means that the same current flows through all the components in the circuit. If one component fails or is disconnected, the entire circuit will be interrupted and no current will flow.Rate this question:

What would the total resistance be if we put an infinite number of resistors in parallel?
-
The total resistance would approach zero as the number of resistors in parallel would approach to infinity.
-
The total resistance would approach one as the number of resistors in parallel would approach to infinity.
-
It would approach infinity.
-
None of the above
Correct Answer
A. The total resistance would approach zero as the number of resistors in parallel would approach to infinity.Explanation
When resistors are connected in parallel, their total resistance decreases. As more and more resistors are added in parallel, the total resistance approaches zero. This is because the current has multiple paths to flow through, reducing the overall resistance. Therefore, the correct answer is that the total resistance would approach zero as the number of resistors in parallel approaches infinity.Rate this question:

The wires that bring electricity to a motor circuit are likely to be labeled on a schematic with the letter..
-
L
-
T
-
W
-
C
Correct Answer
A. LExplanation
The letter "L" is likely to be used to label the wires that bring electricity to a motor circuit on a schematic. This is because "L" is commonly used to represent the line or live wire in electrical diagrams and schematics. The line wire is the wire that carries the current from the power source to the motor, so it is important to label it correctly for proper understanding and troubleshooting of the circuit.Rate this question:

A part of a circuit is said to be grounded if it is connected to
-
An open switch
-
A metal frame
-
The power source
-
A common wire
Correct Answer
A. A metal frameExplanation
A part of a circuit is said to be grounded if it is connected to a metal frame. Grounding a circuit means connecting it to the earth or a conductive object, such as a metal frame, to provide a path for electric current to flow safely into the ground in case of a fault or excess voltage. This helps protect against electrical shock and prevents damage to the circuit or connected devices.Rate this question:

This diagram shows how the pushbuttons affect the opening and closing of the four sets of motor starter relay contacts. How does pushing the "FORWARD" button affect the two sets of contacts labeled "F"?
-
The closed contacts open
-
The open contacts close
-
Both sets of contacts reverse
-
Both sets of contacts remain unchanged
Correct Answer
A. Both sets of contacts reverseExplanation
Pushing the "FORWARD" button causes both sets of contacts labeled "F" to reverse. This means that if the contacts were closed, they will open, and if they were open, they will close. This reversal of contacts is likely to change the flow of current or the direction of movement in the motor starter relay circuit, resulting in a different operation or function.Rate this question:

Which of the following is not a type of electrical diagram?
-
Pictorial drawing
-
Wiring diagram
-
Component diagram
-
Schematic Diagram
Correct Answer
A. Component diagramExplanation
A component diagram is not a type of electrical diagram. Electrical diagrams are used to represent the electrical connections and components in a system, such as wiring diagrams and schematic diagrams. However, a component diagram is typically used in software engineering to represent the components and their relationships in a software system. It is not specifically related to electrical systems.Rate this question:
