2 cards from this section. Quick, good the night before a test.
What is the phase relationship in a pure resistive circuit?
Think about how voltage and current behave simultaneously.
What is the formula for calculating impedance in an LCR circuit?
Recall the components of impedance.
What is the formula for impedance in an LCR circuit?
Think about how we represent inductive and capacitive effects in circuits.
In a purely capacitive circuit, does current lead or lag voltage?
Recall the phase relationships we've discussed.
Calculate the total impedance of a series LCR circuit with resistance of 10Ω, inductive reactance of 8Ω, and capacitive reactance of 6Ω.
Use the impedance formula to solve for Z.
Draw the waveform of voltage and current in a purely inductive circuit and explain the phase relationship.
Focus on how the peaks align in a time graph.
