Question

Part 2 -Jacob's ladder A Jacob's ladder is a continuous about three million Newtons per Coulomb). We will all watch the Jacob's ladder video ( then each group will choose one of the questions below and take 5 minutes to discuss the question and find an answer One representative from each group will present the results of the group to the class spark that rises between two conductors. (The dielectric strength of air is Estimate the voltage required for a Jacob's ladder to spark. Since it's plugged into the wall (120v AC), how is the voltage you estimated possible? 1) What is the potential difference between the two conductors when they are closest together about when they are farthest apart? What 2) 3) Why does the spark initially start at the bottom? 4) Why does the spark rise? 5) Why do you hear it? Tutorial 3: Electric Potential

Explanation / Answer

1. E=V/d

Voltage V=Ed

2. The potential difference between two conductors when are very nearer is minimum and the potential difference when both conductors are away is maximum.

3. The spark intially starts at bottom as when voltage is given the positive electrons tend to move to the negative side and thus breaking the air, creating plasma the medium. At the bottom the distance between the conducting wires is less. So, the spark starts at bottom.

4. It raises up as the heated air around the plasma is less dense than the air above that.

5. Since the electrons break through to move towards negatively charged side, this movement makes a sound which we hear.
