Phy
c1 - superposition principle --> Fe = (Fx2 + Fy2)1/2
- calculation [ find the angle]
- electric field E = KeQ/r2 =F/q
C2 - V = Q / 4.pai.Enaut.d [one point/multipoint]
- Vab = lVa+Vbl
- Pe = KeqQ/r2 [potential E]
C3 - current
- ohm's law
- power
- resistance
c4 - c = Q/v = delta A / d
- paralalel / series circuit
