EACH of these statements CAN be true or false. They ALL depend on the situation, and on the components of the particular circuit.
For each of these statements, I can give you the diagram of a circuit in which the statement is true, and I can give you the diagram of another circuit in which the same statement is false.
These choices are usually true:
-- Changing the frequency does not affect the current.
-- Increasing the resistance decreases the current.
-- Increasing ΔVmax increases the current.
These choices are usually false:
-- Increasing the frequency increases the current.
-- Changing ΔVmax does not affect the current.
-- Changing the resistance does not affect the current.
-- Increasing ΔVmax decreases the current.
-- Increasing the resistance increases the current.
-- Increasing the frequency decreases the current.
These choices can go either way just as easily:
-- Voltage leads current.
-- Current and voltage are in phase.
-- Current leads voltage.
