Alexandra was preparing to go on a hike in the woods. She gathered the equipment she would need and placed it on the kitchen counter. By chance, she placed her compass near an electrical outlet. Although the compass was not moving, the compass needle turned because ______.

the electric current in the outlet produced a magnetic field

the kitchen counter was made of a magnetic substance

the compass could only be used outdoors

the kitchen had a microwave oven

In a closed circuit containing one resistor and a battery, if the voltage in the battery increases, the current going through the resistor increases. Why does this occur?

As the electrons are pushed more by the battery, they move faster through the circuit.

As the electrons are sped up, they bunch closer together.

As the electrons have more energy, they vibrate more rapidly.

As the distance around the circuit increases, the electrons take longer to travel around.
