Resistance to the flow of electrons in a conductor causes a loss of _____ as heat.  
Makovka662 [10]

Free electrons seem to travel via the conductors with a certain degree of friction, or opposition to the motion. This opposition to the motion is more precisely known as resistance.

The amount of the current in a circuit relies on the concentration of voltage accessible to encourage the electrons, and also the amount of resistance in the circuit to oppose the flow of electron. Resistance to the flow of electrons in a conductor causes a loss of energy in the form of heat.

<h2>Answer is option "c"</h2>

Explanation:

  • Earth is the main planet in the solar system with a climate that can continue life. The cover of gases contains the air that we inhale as well as shields us from the impacts of warmth and radiation exuding from the sun. It warms the planet by day and cools it around evening time.

These can likewise portray the climate in a specific spot, yet while the climate can change in only a couple of hours, the atmosphere changes over a more drawn out range of time.  
  • Earth's worldwide atmosphere is normal of territorial atmospheres. The worldwide atmosphere has cooled and warmed since the beginning. Today, we are seeing strangely fast warming. The logical accord is that ozone harming substances, which are expanding a result of human exercises, are catching heat in the atmosphere.
  • Hence, the right answer is option c " reduces the temperature extremes between day and night recycles."
