Electricity Equations

Question 1

Equation for charge

Answer 1

Charge = current x time
Q = I x t

Question 2

Equation for energy

Answer 2

Energy = charge x potential difference
E = Q x V

Question 3

Equation for power (with current)

Answer 3

Power = current x potential difference
P = I x V

Question 4

Equation for potential difference

Answer 4

Potential difference = current x resistance

V = I x R

Question 5

Equation for power (with energy)

Answer 5

Power = Energy / time
P = E/t

Question 6

Equation for energy (with 3 parts)

Answer 6

Energy = current x voltage x time
E = I x V x t
