1. "Axial is Always twice" (A = 2) E_axial = 2kp/$r^{3}$ vs E_equatorial = kp/$r^{3}$ — "Axial" and "two" both start with sounds from the alphabet beginning. The A in Axial reminds you of 2 (looks like a tent with two legs).

2. "CaPS vs ReSiP" — Capacitor/Resistor Series-Parallel flip

• Capacitors: Parallel = Sum (C_eq = $C_{1}$+$C_{2}$); Series = Reciprocal (1/C_eq = 1/$C_{1}$+1/$C_{2}$)
• Resistors: Series = Sum (R_eq = $R_{1}$+$R_{2}$); Parallel = Reciprocal (1/R_eq = 1/$R_{1}$+1/$R_{2}$)
• They are exactly opposite — CaPS vs ReSiP.

3. "VQ-CV Rule" for dielectric insertion

• Battery V-Connected → V constant, C increases
• Battery Q-Disconnected → Q constant, V decreases

4. "WPC" for Gauss's law E-field dependence

• Wire → E ∝ 1/r (cylindrical)
• Plane → E = constant (planar)
• Conducting sphere → E ∝ 1/$r^{2}$ (spherical) Order of decreasing r-dependence: 1/$r^{2}$ > 1/r > constant.

5. "NECA" — Properties of charge

• Not destroyable (Conservation)
• Equal units only (Quantization, q = ne)
• Combines algebraically (Additive)
• Attracts opposites, repels likes

6. "PLANO" — Potential on different dipole lines

• Polar axis (axial): V = kp·cosθ/$r^{2}$ → non-zero
• Perpendicular (equatorial): V = 0 (zero) Remember: equatOriAL = zerO (the O in zerO matches equatOriAl).
