Check all choices below that are correct. increasing the frequency increases the current. changing the frequency does not affect the current. voltage leads current. current and voltage are in phase. 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 resistance decreases the current. increasing δvmax increases the current. current leads voltage. increasing the frequency decreases the current.

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.
