If several resistors are connected in series in

an electric circuit, the potential difference across

each resistor

(1) varies directly with its resistance

(2) varies inversely with its resistance

(3) varies inversely with the square of its

resistance

(4) is independent of its resistance

varies directly with its resistance

Explanation:

In a serious circuit, the potential difference across each resistor varies directly with its resistance. The sum of the potential drops across all the resistors equals the applied potential

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.
