In the diagram to the right, the battery provides 12 V to the circuit made up of three identical light bulbs. When the switch is closed the voltage across bulb A will be A. 12 V.
B. 2 V.
C. 6 V.
D. 4 V.

where’s the list ? the question is incomplete

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
