Physics
Charge
Q
Coulombs
Power
efficiency = Useful power output / Total power input
P=IV
P=1^2 x R
Energy = power x time
I-V characteristics
Ohmic conductor
R is constant with I
only if temp is constant
Non Ohmic conductor
Diode
current can only flow i one direction
filament bulb
as temp increases ions gain KE and vibrate more
harder for electrons to pass
