What is displacement current?
Think about currents that occur when electric fields vary.
State the equation for displacement current.
Consider the relationship that includes electric flux.
What does displacement current help to define?
Focus on how electric fields change.
True or False: Displacement current is a traditional current that involves movement of charges through a conductor.
Remember the definition and its implications.
An ideal capacitor with plates of area A and separation d is charged with a constant current. Derive an expression for both conduction and displacement currents when the potential difference is V.
Consider relevant relations between charge, voltage, capacitance, and displacement currents.
Describe how displacement current would affect the operation of a wireless power transfer system using resonant inductive coupling.
Think about the underlying principles of electromagnetic induction and field propagation.
