Q

Which statement(s) about parallel circuits is correct?

Circuit components that are connected in such a way to provide a single current path through each component are said to be connected in parallel.

For a circuit to be considered a parallel circuit, there must be at least two paths for the current to flow.

Parallel circuits must contain more than one voltage source.

The current through any branch of a parallel circuit will be less than the total circuit current.
