Equtions

Question 1

Power=

Answer 1

Power = work done ➗ time taken

P=E➗T

Question 2

Energy transferred=

Answer 2

Energy transferred = charge moved x potential difference (E=QV)

Question 3

Charge =

Answer 3

Charge = current x time (Q= IxT)

Question 4

Potential difference =

Answer 4

Potential difference = current x resistance (V=IR)

Question 5

Power =

Answer 5

Power = energy transferred➗time taken (P=E ➗T)

Question 6

Electrical power= (x2 equations)

Answer 6

Electrical power = current x potential difference (P=IV)

Electrical power= (current)^2 x resistance
P=I^2xR
