Concept Review The _______________is the same everywhere in a simple series circuit The equivalent ______________of a series circuit is the ___________of the resistances A ____________ ___________ is a series circuit used to produce a voltage source from a higher-voltage battery

Concept Review Con’t In a __________ circuit, the total current is equal to the sum of the currents in the branches A __________ or _________ _________, placed in series with appliances, creates an open circuit when dangerously high currents flow.

Concept Review Con’t What happens to the current in the other two lamps if one lamp in a three-lamp series circuit burns out? In a parallel circuit? Why does the equivalent resistance decrease as more resistors are added to a parallel circuit? Does it decrease in a series circuit? Why is household wiring done in parallel instead of series?
