Question Answer
Power Power (W) = Voltage (V) x Current (A) P = I x V
Voltage Voltage (V) = Current (A) x Resistance (R) V = I x R
Charge Charge (C) = Current (A) x Time (s) Q = I x t
Energy (1) Energy (J) = Voltage (V) x Charge (C) E = V x Q
Energy (2) Energy (J) = Voltage (V) x Current (A) x Time (t) E = V x I x t
Transformer Equation Vₚ / Vₛ (V) = Nₚ / Nₛ (Number of turns)
Total Cost Number of units x Cost per unit
