a) The full bridge inverter as shown in Figure 1 below, has a switching sequence that produces a square wave voltage across a series RL load. The switching frequency is 60 Hz, Vdc = 100 V, R = 10 \Omega and L = 25 mH. Derive an expression of the load current. b) A square wave inverter single phase has the input of DC voltage of 150 V. The value of R = 20 \Omega and L = 30 mH with the output frequency of 50 Hz. Determine i) Fundamental output voltage of inverter. ii) The THD output voltage (considered for three harmonics) iii) The THD output current (considered for three harmonics) iv) The power absorbs by the load (considered for three harmonics)

Locations/positions in the DNA of cuts for PGLO digested with EcoRI & HindIII EcoRI 2063 bp Hindill 2114 bp HindIII 1465 bp Plasmid = 5371 bp list out the resulting fragment sizes after the DNA digest. For example, in column 1 we are looking at the resulting fragment sizes when the PGLO plasmid is digested (cut) by the Enzyme Pairs EcoRI & Hindill EcoRI & Hindill restriction indIII & EcoRI & EcoRI & enzymes EcoRI amHI BamHI BamHI PGLO PAMP and HindIII. AMP PGLO PAMP Fragment 4722bp sizes (bp) 598 bp 51 bp Based on the plasmid DNA sequence and restriction sites, we predict to see three fragments of size 4722, 598, Total #bp 5371 bp in plasmid Fragments smaller than 400 bp very hard to see on the gels that we use and because of the low concentration of plasmid that we use in the analysis.

10. Refer to parallelogram ABCD. If AB = 8 cm, what is the perimeter of the parallelogram? 6 cm 11. BALANCING Nikia, Madison, Angela, and Shelby are balancing on an X-shaped floating object. To balance, they want to stand so they are at the vertices of a parallelogram. To achieve this, do all four of them have to be the same distance from the center of the object? Explain. 12. FORMATION Four jets are flying in formation. Three of the jets are shown in the graph. If the four jets are located at the vertices of a parallelogram, what are the three possible locations of the missing jet? 13.
