23.  Steps to Calculate Electric Potential
24.  To calculate the electric potential at a point in an electric field created by one or more point charges, you can follow these steps:
25.  
26.  
27.  Identify the Source Charge: Determine the charge(s) creating the electric field.
28.  
29.  
30.  Measure the Distance: Measure the distance from the point of interest to each charge.
31.  
32.  
33.  Apply the Formula: Use the formula for electric potential given above for each charge.
34.  
35.  
36.  Sum the Potentials: If there are multiple charges, the total electric potential at the point is the algebraic sum of the potentials due to each charge.

44.  Example Calculation
45.  Let’s apply this process with a practical example. Consider https://lovely-tulip-rgp0p3.mystrikingly.com/blog/add-a-blog-post-title ( Q_1 = 2 , \mu C ) located at the origin (0,0) and you want to calculate the electric potential at a point ( P ) located 0.5 meters away from the charge.
46.  
47.  
48.  
49.  Identify the Source Charge: ( Q_1 = 2 \mu C = 2 \times 10^ -6 C )
50.  
51.  
52.  Distance: ( r = 0.5 m )
53.  
54.  
55.  Apply the formula:
56.  
57.  [
58. V = \frack \cdot Q_1r = \frac(8.99 \times 10^9) \cdot (2 \times 10^ -6)0.5 = 35,960 , V

60.  
61.  
62.  
63.  Thus, the electric potential at point ( P ) is approximately 35,960 volts, indicating that work would be required to move a positive charge to this point from infinity.
