Exam 5: Capacitors and Rc Time Constants

____________________ is the property of a circuit, or circuit component, that allows it to store electrical energy in electrostatic form.

Capacitance and ____________________ values are usually written directly on large ac oil-filled paper capacitors.

Good conductors have many free electrons in their structure.

The ____________________ capacitor has two metal plates with an air dielectric.

Any inductance coil is really a combination of inductance and resistance in series.

Explain how to connect electrolytic capacitors.

Describe why having firmly held electrons in their electron shell makes a material a good insulator.

A positive temperature coefficient indicates that the capacitance will decrease with an increase in temperature.

Explain the RL exponential current curve.

____________________ capacitors consist of a ceramic dielectric and silver plates.

What is the standard unit of measure for capacitance and how is it defined?

All capacitor manufacturers use a standard set of color codes.

Once charged, a capacitor can remain charged forever.

Describe how the value, such as "105K" marked on a film-type capacitor can be read.

If an insulating material, known as a dielectric, is placed between two plates of a conducting material, the resulting assembly is a(n) ____________________.
