Questions & Step-by-Step Solutions
If a capacitor is connected to an AC source, what happens to the current through the capacitor?
Steps
Concepts
Capacitive Reactance
– In an AC circuit, capacitors oppose changes in voltage, causing the current to lead the voltage by 90 degrees.
Phase Relationship
– Understanding the phase difference between current and voltage in capacitive circuits is crucial for analyzing AC behavior.
