Equations P5 Flashcards
1
Q
P = E / T
A
Power (W) = Energy (J) / Time (S)
2
Q
P = I × V
A
Power ( W) = Current (A) × Voltage ( V)
3
Q
P = I² × R
A
Power ( W) = Current² ( A) × Resistance (Ohms)
4
Q
E = P × T
A
Energy (J) = Power ( W) × Time (s)
5
Q
E = Q × V
A
Energy (J) = Charge (C) × Voltage (V)
6
