In a RLC circuit we have the following in series: a one-and-a-half ohm resistor, a 12 mH inductance coil, and a 1.6 micro-farad capacitor. If the circuit begins to oscillate at time equal to zero, at what time will the amplitude of the charge be at half of its initial value? a. cannot be calculate as the initial charge value is unknown O b. 11 seconds O c. 11 milli-seconds O d. 11 micro-seconds
