Exam 2: Voltage, Current, and Resistance

The adjustable contact of a 1 k linear potentiometer is set at 3/4 of full rotation from the lower-end terminal. What is the resistance between the adjustable contact and the upper-end terminal?

The nucleus contains protons and electrons, each with an opposite charge.

Valence electrons of an atom determine the:

What is the maximum resolution of a 3 1/2-digit DMM when measuring volts?

Which is NOT one of the three categories of materials used in electronics?

The typical resistor to use for higher power applications would be the:

The copper atom contains 29 free electrons.

The force that causes conductor electrons to move is:

Transistors used as switches

DMM's are the most widely used type of electronic measuring instrument because of:

Valence electrons are tightly bound in insulators.

What is the tolerance of a resistor manufactured to a minimum value of 5445 ohms and a maximum value of 5555 ohms?

The materials with the fewest free electrons are classified as:

Electrons are negatively charged particles, and are contained in the nucleus of the atom.

The fifth band in a precision resistor represents the:

To measure current with an ammeter, connect the ammeter:

Which of the following is a true statement?

The smallest particle of an element that still retains the characteristics of the element is called an atom.

Determine the tolerance and resistance of a resistor labeled 470KJ.

Ground is the reference point in electric circuits and has a potential of with respect to other points in the circuit.
