Explanation:
<u>Electric Field and Potential Difference</u>
There are several conditions that must be met for a spark to be created into an air gap. Once the physical conditions are fixed, a minimum electric field is necessary for the spark to be initiated. Let s be the separation between the electrodes and V their potential difference. The electric field is
a.)
Solving for V
The separation is
Thus the potential difference is
b.) If the separation was greater, the applied voltage needs to be greater if the electric field has to be constant. One possible measure to keep electrodes as close as possible is to build them as sharp edges. It gives the spark an easier path to travel to.
If the separation is 0.05 inches =0.00127 m
Answer:
Explanation:
The data given in the question is
Charge : q =
Electric field Strength : E =
Electrical potential Energy : U =
Let, the distance be "d"
So, the formula for Electrical potential energy is
Simplified formula for distance become
