Which of the following statements is FALSE?
Wire length and size never matter when considering resistance.
Wires are made of conductive metals like copper.
Wires offer low resistance to the flow of electricity.
Most wires have a color coating for insulation and identification.
An electrical ground is...
the bottom point on which circuits are constructed
the 0V or "-" side of a battery or other voltage source
a board used as a frame for building circuits
all of the above
Advantages of printed circuit boards include...
metal strips are "printed" on the surface to make interconnections
they are a stable platform for mounting components
the allow circuits to be made smaller and less expensive
all of the above
Which of the following would all be connected in a series?
A lamp and a switch on the wall controlling it.
String of holiday lights in which you can take a bulb out and the rest of the lights stay lit.
Two lamps in different rooms of a house.
The air conditioner and microwave oven in your home.
Which of the following would all be connected in parallel?
A lamp an a switch on the wall controlling it.
The streetlamps in your neighborhood.
A string of holiday lights that all go out if a bulb is missing.
None of the above.
It is better to connect lamps in a parallel circuit configuration when...
the power source can supply enough current but not enough voltage to light them all
if one bulb burns out, you want the others to stay lit
you are also adding switches to control each lamp separately
all of the above
A short circuit is...
a special condition that improves circuit performance in most cases

shortest path between two points in a circuit
all of the above
Solder is...
glue that holds components in place, it resists the flow of electricity
always applied by hand
