Reduce the following block diagrams using the block diagram reduction method.

After solving for the total resistance, and the applied voltage being a given for the circuit, the next logical step is to .....? so that individual component voltages and currents can be found.

Explain why the graph does or does not have an Euler circuit. If it does, specify the nodes within the circuit Figure i: An undirected graph has 6 vertices, a through f. 5 vertices are in the form of a regular pentagon, rotated 90 degrees clockwise. Hence, the top vertex becomes the rightmost vertex. From the bottom left vertex, moving clockwise, the vertices in the pentagon shape are labeled: a, b, c, e, and f. Vertex d is above vertex e, below and to the right of vertex c. Undirected edges, line segments, are between the following vertices: b and c; b and a; b and f; b and e; a and c; a and d; a and f; c and d; c and f; d and e; and d and f.

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.
