Electrical Power Equations

Question 1

what is the equation for charge transferred?

Answer 1

charge transferred = current x time
coulombs = amps x seconds
Q = A x S

Question 2

what is the equation for power?

Answer 2

power = energy / time
watts = Joules / seconds
P = E / t

Question 3

what is the second equation for power?

Answer 3

power = current x potential difference
watts = amps x volts
P = I x V

Question 4

what is the equation for energy transferred?

Answer 4

energy transferred = potential difference x charge
Joules = volts x coulombs
E = V x Q
