a complete path
How can a circuit achieve a continuous flow of electrons?
For a continuous flow of electrons, there must be a complete circuit with no gaps.
a circuit in which devices are arranged so that charge flows through each in turn
What happens to current in other lamps if one lamp in a series circuit burns out?
If one device fails in a series circuit, current in the whole circuit ceases and none of the devices will work.
a circuit in which each electrical device is connected to the same two points of the circuit
What happens if one device in a parallel circuit fails?
In a parallel circuit, each device operates independent of the other devices. A break in any one path does not interrupt the flow of charge in the other paths.
