Robotics - Lessons A1-A3 Review

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
