Exam 18: Capacitive Reactance

The symbol for capacitive reactance is C_X.

The symbol for ______________ reactance is X_C.

For a capacitor, the charge and discharge current flows to and from the plates and through the dielectric.

A measure of a capacitor's opposition to the flow of alternating current is

What is the total capacitive reactance in a series circuit if three capacitors offered 150 ? of reactance each?

When analyzing electronic circuits, capacitors are often treated as an open for dc and as a short for ac.

How much X_C will there be if the capacitance is 10 ?F and the frequency is 1400 Hz?

In a capacitive circuit, instantaneous voltage and current are 180° out of phase.

Because of the inverse relation between X_C and f or C, the graph of X_C versus C is

The base unit for capacitive reactance is the siemens.

X_C equals

For parallel reactances, the combined reactance is calculated by

For a capacitor, the charge and discharge current flows to and from the plates not through the ______________.

In the formula for capacitive reactance, the constant factor 2? is always

A very common use of a capacitor is to provide little opposition for ac voltage but to block any dc voltage.

When analyzing electronic circuits, capacitors are often treated as

Series or parallel capacitive reactances are combined in the same way as capacitances.

Which of the following is correct?

When a capacitor charges and discharges with a varying voltage applied, alternating current can flow.

When analyzing electronic circuits, capacitors are often treated as a ______________ for ac.
