Q
Electrical Work (Equation) - when a current flows
A
E = VIT
energy = potential difference x current x time
2
Q
Electrical Energy (Equation)
A
E = Q x V
energy = charge x potential difference
3
Q
Power
A
- is the rate of energy transfer (or work done)
- the power (measured in watts) = work done (in joules)/ time (in seconds)
4
Q
Energy Transferred
A
the faster that energy is transferred (or work is done), the higher the power
energy transferred (kw/h) = power (kw) x time (h) E = p x t
energy transferred (J) = power (w) x time (s) E = p x t
