Question

why are conductors energy - efficient?
○ high resistance
○ no electrons
○ block energy
○ low resistance
how do insulators conserve energy? *
○ conduct electricity
○ increase current
○ generate heat
○ prevent heat loss
which is a natural conductor? *
○ wet soil
○ dry wood
○ quartz
○ air

Explanation:

1. For the first question: Conductors allow electric current flow; wet soil has dissolved ions enabling conductivity, while others are insulators.
2. For the second question: Insulators have high resistance to heat/electricity transfer, so they stop unwanted heat loss to conserve energy.
3. For the third question: Conductors have low electrical resistance, meaning less energy is wasted as heat when current flows, making them energy-efficient.

Answer:

1. Wet soil
2. Prevent heat loss
3. Low resistance
