Why is Bulb A lit up but not Bulb B in this circuit?

• The battery is probably too weak to power two lights at one time

• Bulb B is probably not working or not screwed in completely

• The wire going to Bulb B is probably connected backwards

• Bulb B is not in a complete circuit, but Bulb A is

Why is the light bulb not lit even though the wires connect the battery to the bulb?

• The battery is probably dead

• The light bulb is probably not working or not screwed in completely

• One of the wires is probably broken or hooked up backwards

• Both wires connect to the same side of the battery

When the switch in this diagram is open (as shown), which of these conditions will occur?
