____ are typically found as axial-lead packages.

The International System of Units has ____ base units.

Each ____ is made up of a nucleus surrounded by orbiting electrons.

____ states that the voltage across a component is equal to the resistance of the component multiplied by the current through the component.

Rubber is an example of:

A proton is:

The typical issue when measuring current is that the ____ must receive the exact same current as the resistor to be measured.

A device with hidden interconnections on which we can build a prototype circuit is a ____.

A circuit built functionally the same as a circuit that is to be tested is a ____.

For current to flow, we need to replenish the ____ at the negative end so they can flow to the positive end; as these flow, the charge flows.

The atomic number of an element is the number of ____ in the nucleus of an atom of that element.

The unit(s) for resistance is/are ____.

Typically, ____ vary between two discrete values in much the same way that a light switch has two levels, "off" and "on".

The signal on a CD is sampled ____ times each second.

Assigning the digit 1 to a logic HIGH and digit 0 to logic LOW is called ____.

The hexadecimal number system is based on powers of ____.

Which of the following terms does NOT apply to digital signals?

A ____ system is a system of writing numbers where the value of a digit depends not only on the digit, but also on its placement within a number.

After the binary system, ____ numbers are the most often used in digital applications.

____ is the fraction of the total period that a digital waveform is in the HIGH state.
