1.Utilize an appropriate R-C circuit powered by a 120 V DC source. This RC circuit will be the energy source to power a single Neon Lamp. 2. Neon and other gas-based lamps often require a threshold voltage before they turn "on", i.e. emit light. The neon lamp you will use has a turn-on voltage of 70 V. In the provided LTspice model of such a neon lamp, you can explore how this light turns on and off (i.e. the current through the lamp is high when the lamp is on), when it is powered by a pulsed voltage source. Play around with the pulsed source parameters to investigate the lamp's behavior. However, keep the lamps LIspice parameters fixed (i.e. do not change the attributes of the lamp). 3. Using the RC circuit Power your Neon Lamp so that it turns on every 0.1 seconds (10 Hz frequency). The time for which it remains on is not critical, but should obviously be much less than 0.1 seconds.
