ELECTRICITY
Power:
power = voltage x current
(current = 'I')
Voltage:
voltage = current x resistance
Charge:
charge = current x time
(charge = 'Q')
Energy:
energy = voltage x current
Efficiency % :
efficiency = (useful energy out / total energy in) x 100
GPE:
Gravitational potential energy = mass x gravity x height
Kinetic Energy :
kinetic energy = 0.5 x mass x velocity²
