Breadboard. . .
Choose the best answer
Remove the need to solder components together
Contain internal connections
Must be connected to an external power
Have vertical rails for power distribution
All of the above
What should you do if you notice your batteries or components are getting warm?
Leave it as it is, it will cool down on its own
Disconnect the battery
Remove the component such as a resistor to the circuit
None of the above
Static electricity
Same process that produces lightning
Dangerous to electronic components
More likely when working on a plastic surface
Can exist even if you don’t see or feel a spark
All of the above
“The circuit is grounded” means
The circuit is touching metal
The path of the circuit starts with the end wire connected to the positive of the battery.
You touched something metal prior to touching the circuit
The circuit contains a connection to the negative terminal of the battery
None of the above
Electricity has a positive charge, a negative charge, and a neutral charge.
True
False
Voltage can be thought of as how fast the work is being done
True
False
All holes in the breadboard are internally connected
True
False
Placing a resistor in a circuit can
Speed up the flow of electricity so the circuit works quickly
Prevent a short circuit
Help components receive more current so they work more reliably
Cause the flow of electricity to stop until the resistor is removed
A component’s forward voltage (Vf)
The same for every component
The minimum voltage required to turn on the component
The excess amount of voltage in the circuit
The maximum voltage a circuit can tolerate safely
None of the above
To calculate the forward voltage (Vf) required for a circuit
Add the Vf values for all components
Multiply the Vf values for all components together
Subtract the value of the resistor(s) from the total Vf of the other components
Determine the Vf value for the component in the circuit with the largest Vf value
An LED can be safely placed in a circuit alone
True
False
Resistors must be placed before other components in the circuit
True
False
Which of the following describes a series circuit
Used in common electronics such as remote controls
Consists of a single path from battery positive to battery negative
Must include multiple components
Have minimal voltage requirements
All of the above
Parallel circuits
Require only one resistor
Remove the need to calculate forward voltage(Vf)
Allow for the full voltage of the battery to run across each branch of the circuit
Always require a larger battery than a series circuit
None of the above
Ohm’s Law
Is a theoretical math equation
Can be used to calculate forward voltage(Vf)
Can be used to determine if a circuit should be built in series vs, in parallel
Tells us the value of the color bands on the resistors
None of the above
Common electronics objects in your everyday life are built as parallel circuits
True
False
One resistor is sufficient for a parallel circuit
True
False
