Exercise 102

Avg difficulty 2.5

Suppose we have an RLC circuit with a resistor of 100 milliohms (0.1 ohms), inductor of inductance of 50 millihenries (0.05 henries), and a capacitor of 5 farads, with constant voltage.

  1. Set up the ODE equation for the current II.
  2. Find the general solution.
  3. Solve for I(0)=10I(0) = 10 and I′(0)=0I'(0) = 0.
