Question

1. Can one use energy conservation with electricity concepts?

2. Write down a phenomenon that involves potential or potential difference?

3. How is potential in static electricity related to potential in current-carrying circuits?

Answer 1

1- In the future, civilization will be forced to research and develop alternative energy sources. Our current rate of fossil fuel usage will lead to an energy crisis this century. In order to survive the energy crisis many companies in the energy industry are inventing new ways to extract energy from renewable sources. While the rate of development is slow, mainstream awareness and government pressures are growing. This page contains articles about the future of energy technologies.

While solar-power electric hybrid vehicles are a proven success story on the roads, the time is ripe for the appearance of solar-electric watercraft. Already a pontoon boat - Loon - is available in the market. It is solar-electric powered and can seat eight passengers. Now a smaller one - the purely electric run, Infinyte I4 - is the new kid in the block.

2- Difference between potential and potential difference

• Electric potential energy is a type of potential energy that results from Coulomb forces. The potential energy (UE) between charges q and Q can be calculated as a function of distance between the charges (r): UE(r)=qQ4??0r.

• The formula for potential energy can be modified for potential between many charges, so long as the interactions of each charge with every other charge in the system are considered. For example, potential between three charges can be solved using the following formula: UE=14??0r(Q1Q2r12+Q2Q3r23+Q1Q3r13)

• 3 - relationship between electric field and potential

• The electric field is a measure of force per unit charge; the electric potential is a measure of energy per unit charge.

  For a uniform field, the relationship between electric field (E), potential difference between points A and B (?), and distance between points A and B (d) is: E=???dIf the field is not uniform, calculus is required to solve.
