Electricity Equations Flashcards
(6 cards)
1
Q
Equation for charge
A
Charge = current x time Q = I x t
2
Q
Equation for energy
A
Energy = charge x potential difference E = Q x V
3
Q
Equation for power (with current)
A
Power = current x potential difference P = I x V
4
Q
Equation for potential difference
A
Potential difference = current x resistance
V = I x R
5
Q
Equation for power (with energy)
A
Power = Energy / time P = E/t
6
Q
Equation for energy (with 3 parts)
A
Energy = current x voltage x time E = I x V x t
