Circuits - series and parallel

When only one lightbulb blows out, an entire string of decorative lights goes out. The lights in this string must be connected in

• series with multiple current pathways

• series with one current pathway

• parallel with multiple current pathways

• parallel with one current pathway

This circuit does not work because…

• the bulbs are not connected properly
• two cells are not powerful enough
• there is a break in the circuit
• the cells are facing each other
