Formulas and Key Relations

2. Electrostatic Potential and Potential Difference

U = kQq/r

V = W/q = kQ/r

V_B - V_C = (W_B - W_C)/q

V = Work done (W) / Amount of charge transferred (q)

1 volt = 1 joule / 1 coulomb

3. Electric Current

i = charge(Q)/time(t)

1 A = 1 C / 1 s

Conventional current flows opposite to electron flow.
