• V = IR (Ohm's Law)
• V = W/Q
• Q = Ne
• I = Q/t
• P = W/t
• F = (kQ1Q2)/d^2
• R = Pl/A
• 1unit = 1kwh = wattage x hours / 1000
• W = E = mc(delta)T

Units

• Force : Newtons
• Power : Wattage
• Work : Joules
• Quantity of Charge : Coulombs
• careful of units; all should be converted to MKS

Constants:

• e = 1.6 x 10^-19
• P = rho constant
• k = constant
• c = specific heat capacity
