electricity equations

Question 1

equation for energy:

Answer 1

energy = power x time

Question 2

energy is measured in:

Answer 2

joules (joules per coulomb)

Question 3

power is expressed in:

Answer 3

watts

Question 4

equation for power:

Answer 4

power = energy/time

Question 5

(electrical) power:

Answer 5

power = current x voltage (P = I x V)

Question 6

charge:

Answer 6

charge = current x time (Q = I x T) (c = a x s)

Question 7

equation for resistance

Answer 7

voltage = current x resistance ( resistance = voltage/ current)

Question 8

equation for energy transferred:

Answer 8

energy transferred = voltage x current x time ( E=V x I x T)
