Chapter 2, Section 6 Flashcards
Define what is an RCL circuit.
A circuit consisting of a resistor (R), capacitor (C), and inductor (L).
What is the resistance to current flow that is caused by the inductor and the capacitor?
Impedance.
What is the unit of measure for an inductor in a circuit?
Henry.
In a circuit that contains an inductor, how does the inductor affect current flow when current is
first applied?
Initially resists change, causing a delay in current buildup.
How is a capacitor electrically different than a battery?
Stores and releases electrical energy without chemical reactions.
What is the physical construction of a capacitor?
Two conductive plates separated by a dielectric.
What are the two electrical properties of a capacitor?
Capacitance and voltage rating.
What is the mathematical formula for XL?
XL = 2(pi)(f)(L)
How is total inductive reactance in a series circuit computed?
By summing individual inductive reactances.
When given a circuit where you have the values of the inductors and the frequency of the
input, how would you determine the total reactance in the circuit?
By summing individual reactances.
How is the total inductive reactance determined in a parallel circuit?
By taking the reciprocal of the sum of the reciprocals of individual reactances.
Write out the mathematical formula for XC.
XC = 1/(2(pi)(f)(C))
What does the
term ELI the ICE man refer to?
Phase relationship in AC circuit.
ELI: Voltage (E) leads current (I) in an inductive circuit
ICE: Current (I) leads voltage (E) in a capacitive circuit.
What is the maximum amount of phase difference that can exist in an RCL plot?
180 degrees.
In a parallel RCL circuit, what is common through all of the components?
Voltage.
