Formulas Flashcards
1
Q
voltage =
A
voltage = current x resistance
2
Q
electrical power=
A
electrical power = voltage x current
3
Q
energy transferred =
A
energy transferred = power x time
or = current x voltage x time
4
Q
refractive index =
A
refractive index = sinI/sinR
5
Q
sin (critical angle)=
A
sinC= 1/refractive index
6
Q
gpe=
A
gpe= mgh
7
Q
power =
A
power = work / time taken
8
Q
pressure difference=
A
pressure difference = height x density x gravity
9
Q
charge=
A
charge = current x time
