Building A Circuit On A Breadboard
- 1.
Breadboards allow for prototyping an electrical circuit without the need to solder the components.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Breadboards are commonly used in electronics to quickly and easily prototype circuits. They have a grid of holes that allow components to be inserted and connected without the need for soldering. This makes it convenient for testing and modifying circuits without the permanent commitment of soldering. Therefore, the statement that breadboards allow for prototyping without soldering is true.Rate this question:

The conductive metal strips on a breadboard
- A.
Contain buss strips commonly used for power connections
- B.
Provide socket strips in the build area to hold components
- C.
Are conductive with low resistance
- D.
All the above
Correct Answer
D. All the aboveExplanation
The conductive metal strips on a breadboard serve multiple purposes. They contain buss strips that are commonly used for power connections, allowing for easy distribution of power throughout the circuit. They also provide socket strips in the build area to hold components securely in place. Additionally, these metal strips are conductive with low resistance, ensuring efficient flow of electrical signals. Therefore, all of the given options are correct.Rate this question:

When observing electrical safety
- A.
Leaving the power connected allows you to monitor the success of the build
- B.
Wearing watches and ring is acceptable while working in low power circuits
- C.
Eye protection is necessary as components may shatter.
- D.
You should always treat the circuit as if it is off
Correct Answer
C. Eye protection is necessary as components may shatter.Explanation
Power should always be removed if possible to prevent shock.
Even in low power circuit when current travels through a conductor it may cause burns or blistering.
Your are vulnerable to flying shards or oils if a component explodes and your eyes are soft targets
You should always be cautious and treat the circuit as if it is energized.Rate this question:

In preparing to build on a breadboard you should.
- A.
Simply look at the schematic and begin the build
- B.
Never assume the test equipment and components are functional
- C.
ignore any burn marks as you are only experimenting on the circuit.
- D.
Assume all jumper wired and connectors are intact
Correct Answer
B. Never assume the test equipment and components are functionalExplanation
When preparing to build on a breadboard, it is important to never assume that the test equipment and components are functional. This means that you should always check and test the equipment and components before starting the build. Assuming that they are functional without testing them can lead to potential issues and errors in the circuit. It is always better to be cautious and ensure that everything is working properly before proceeding with the build.Rate this question:

There is only one proper method to building a circuit on a breadboard.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
You may use any method you desire as long as the circuit meets you prototypes schematicRate this question:

When connecting buss or socket strips the jumper wires should be
- A.
Long enough to make the connection yet short enough to prevent complications
- B.
Wrapped in a coil to prevent interferencing with the other components
- C.
As long at the test instrument's leads to decrease resistance
- D.
Soldered to the components to ensure conductivity
Correct Answer
A. Long enough to make the connection yet short enough to prevent complicationsExplanation
Short wires have the advantage of not being easy to entangle as well as having a lower chance of induction.
Wrapping the wires in a coil effectively makes an inductor which may impact other components.
Long wires increase resistance and impedance in the circuit.
The purpose of a breadboard is to allow solderless connections.Rate this question:

When installing a component, you should
- A.
Place both ends of the leads in the same socket set.
- B.
Not be concerned about observing polarity in low-power circuits
- C.
Plan ahead to allow connections with other components
- D.
None of the aboves
Correct Answer
C. Plan ahead to allow connections with other componentsExplanation
Placing both ends of a component in the same socket strip effectively "shorts" around the component.
Polarity should always be observed when connection a component. Failing to do so may blow the component or block current.
Always have a plan when building and look ahead to allow room for other componentsRate this question:

Components installed in parallel on a breadboard will share the same socket strip at both ends.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
When components are installed in parallel on a breadboard, it means they are connected to the same power source or ground. This connection is made through the socket strip on the breadboard, which runs horizontally across the board. Therefore, all components installed in parallel will share the same socket strip at both ends, making the statement "True".Rate this question:

When installing an ammeter you should
- A.
Connect it in parallel with the component to be tested
- B.
Install the instrument in series with the current path
- C.
Place a resistor in series with the ammeter to prevent damaging the device
- D.
Set the multimeter to the ohms position and place in series to measure opposition to current flow
Correct Answer
B. Install the instrument in series with the current pathExplanation
Ammeters are connected in within the circuit in series with the path they are measuring
Setting the meter to the ohms position within the path will damage the multimeter.
The ammeter has a low internal resistance and placing an extra resistor in series will increase that resistance and not provide a proper reading.Rate this question:

It is recommended that the last connection in the circuit should be the "hot", or positive, terminal for the power supply.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The last connection in the circuit should be the "hot" or positive terminal for the power supply because this ensures that the current flows in the intended direction and that the circuit functions properly. If the last connection is made to the negative terminal, it would result in reverse polarity, which can lead to malfunctioning or damage of the circuit components. Therefore, it is important to connect the positive terminal last to ensure correct polarity and safe operation of the circuit.Rate this question:
