4 Concept Maps

Flowchart showing how electric potential is defined and measured from reference point to any location in field

Flowchart showing how electric potential is defined and measured from reference point to any location in field

The map in words

  • Charge at Infinity V = 0
    • Work Done: Point in Electric Field V = W/q
      • Potential Difference: Between Two Points V_AB = V_B - V_A
        • Measured in: Volts V J per C

Flowchart showing how to calculate electric potential from a point charge

Flowchart showing how to calculate electric potential from a point charge

The map in words

  • Point Charge q at origin
    • Distance r: Calculate Potential
      • Use Formula: V = kq/r
        • where k: 9 × 10⁹ N⋅m²/C²
        • Direction: Sign of q
          • Positive q: V is Positive
          • Negative q: V is Negative
