Worksheet 16-RCL Circuit Facts

Question 1

For RCL waveform plots, what are the two electrical properties being measured?

Answer 1

The plots that are being measured are the applied voltage and the current.

Question 2

What is the amplitude relationship between the applied voltage and current in an RCL plot?

Answer 2

In an RCL plot for voltage and current, voltage is normally much higher than the current but they are in phase.

Question 3

What component is always in phase with the applied voltage and current?

Answer 3

Resistor current and voltage plots are in phase with the applied voltage and current.

Question 4

What is the maximum amount of phase difference that can exist in an RCL plot?

Answer 4

The maximum amount of phase differential in any plot is 180 degrees, which would cancel out that signal.

Question 5

In a series RCL circuit, what plot would be common in all of the components?

Question 6

What does the memory devices ELI and ICE refer to?

Question 7

What is the measure of all the total resistance to current flow in an AC circuit?

Question 8

What is the determination in an RCL circuit when the Z vector is plotted either positive or negative?

Question 9

Determine the impedance vector when: 
Resistance = 10Ω
Capacitance = 3μF
Inductance = 5H
Frequency = 60Hz

Question 10

Determine the impedance vector when: 
Resistance = 25Ω
Capacitance = 6pF
Inductance = 2mH
Frequency = 2kHz
