1. write down the differential equation that vC(t) satisfies, keeping the L as an unknown. 2. Write down the characteristic equation of the differential equation you wrote in step 1. 3. Write down the discriminant of the characteristic equation in step 2. 4. The expression for vc(t) satisfies the differential equation you wrote in Step 1. From the format of vc(t), what can you conclude about the discriminant? What value should the discriminant be?
