P3 FORMULAS

charge

charge

charge(C) = current(A) x time (s)

Potential difference

current (A) x resistance (Ohms)

Energy trasnferred

Energy(J) = charge (C) x potential difference (V)

Power

Power (W) = potential difference(V) x current (A) = current² x resistance

energy- general equation

energy(J) = power(W) x time(s)
