1.There is a need for a timing circuit to trip a house alarm. Design an RC circuit that reaches 5 V across a capacitor in exactly 5 s. Your source is 12 dc and you have a 10- μF capacitor available.
2. Find the v (t) that satisfies the following differential equation and initial conditions:
(d2v(t)/dt2) + 4 (dv(t)/dt) + 36v(t) = 0, v(0) = 0 V, dv(0)/dt = 24V/s
