electricity and energy equations Flashcards
1
Q
power, current, voltage
A
power = current x voltage
P=IV
2
Q
current, voltage, energy transferred, time
A
energy transferred = current x voltage x time
E=IVt
3
Q
voltage, current, resistance
A
voltage = current x resistance
V=IR
4
Q
charge, current, time
A
charge = current x time
Q=IT
5
Q
energy transferred, charge, voltage
A
energy transferred = charge x voltage
E=QV
6
Q
work done, force, distance moved
A
work done = force x distance moved
W=Fd
7
Q
gravitational potential energy, mass, gravitational field strength, height
A
gravitational potential energy = mass x gravitational field strength x height
GPE = mgh
8
Q
kinetic energy, mass, speed
A
kinetic energy = 1/2 x mass x speed^2
KE=1/2mv^2
9
Q
power, work done, time
A
power = work done/time
