For a system corresponding mainly to a uniform electric field, the flashover voltage is slightly lower than the breakdown voltage of air alone, for the same electrode gaps. The decrease in the flashover voltage is due to the presence of small air pockets between the electrodes and solid dielectric, the influence of moisture and the non-uniformity of the electric field resulting of the difference between the permittivity of both the solid and that of air. The non-uniformity of electric field increases with the voltage because of the surface charging that takes place in this situation.

Write the Verilog code for a 12-bit shift register with ability to shift left or right, synchronized parallel load, asynchronous reset, and serial output? The register is able to load the 12-bit input value (at the positive edge of the clock) if the load signal is one, shift the value in register one bit to the right (at the positive edge of the clock) if the rss signal is one, shift the value in register one bit to the left(at the positive edge of the clock) if lss signal is one, and reset the value in the register at any time if the rst signal is one. The shift register has two 1-bit output which are the MSB (Most significant bit) and LSB (Least significant bit) of the register at any given time. The priority of the signals is in the order as follows with rst having the highest priority. rst, load, rss, lss. When shift register is shifting the value to the right, the MSB bit takes in the load input MSB bit. When shift register is shifting the value to the left, the LSB bit takes in the load input LSB bit.
