LRC Circuit: Oscillations
Newton’s Second Law: S F = ma can be written as: S F - ma = 0 . With a spring and resistance, this becomes: -kx -bv -ma = 0
This is like the equation we get from Conservation of Energy when we have a capacitor, resistor and inductor: S V = 0 , or (1/C)Q + RI + L dI/dt = 0 ,
where VC = (1/C)Q, VR = RI, and
