First 81 words of the document:

2 Resistors in parallel;
R(T) = R1 x R2 / R1 + R2 Power = Energy Transformed / Time
Current = Charge / Time
Current = Power / Voltage
Series Cercuits;
R(T) = R1 + R2 + R3
Formulae
Voltage = Energy / Charge
Parallel Cercuits;
1/R(T) = 1/R1 + 1/R2 +
1/R3
Electrical Power = Potential Difference x Current
Units = Power x Time
Cost = No. Units x Cost per Unit
Voltage = Current x Resistance
Potential Difference = Energy Transferred / Charge
