What is Electric Potential?
Electric potential is the amount of electric potential energy per unit charge at a certain point in an electric field. In simpler terms, it's like asking: "How much energy does a charge have at this spot?"

🧮 Formula to Calculate Electric Potential (V):
For a point charge, the formula is:

𝑉
=
𝑘
⋅
𝑄
𝑟
V=
r
k⋅Q
​

Where:

V is the electric potential (in volts, V)

k is Coulomb’s constant = 8.99 × 10⁹ N·m²/C²

Q is the charge (in coulombs, C)

r is the distance from the charge to the point (in meters, m)

🔌 Example:
Let’s say you have a charge of 2 × 10⁻⁶ C (2 microcoulombs) and you want to find the potential 0.5 meters away.

=35,960 volts
So, the electric potential at 0.5 m from that charge is 35,960 volts.

🧠 Real-Life Analogy:
Think of it like being on a hill. The higher up you are, the more potential energy you have. In electricity, a point with higher potential means a charge could "roll down" from there — this is essentially how electric circuits work too!
