- You are a journeyman electrician working in an industrial plant. Your task is to connect an inductor to a 480-V, 60-Hz line. To determine the proper conductor and fuse size for this installation, you need to know the amount of current the inductor will draw from the line. The nameplate on the inductor indicates that it has an inductance of 0.1 H. An ohmmeter reveals that it has a wire resistance of 10 . How much current should this inductor draw when connected to the line?A 1 cm2 silicon solar cell has a Maximum current of 20 mA and Maximum voltage 590 mV and is illuminated with sunlight yielding a short-circuit current of 22 mA and open circuit voltage 700 mV. Calculate the fill factor. Fill factor FF=a battery with EMF of 9V and an internal resistance, r=0.24ohms is connected to a load resistance R=16ohms. determine its terminal voltage

Calculate the open circuit voltage at room temperature (VT = 26 mv)A 150V moving iron volt meter intended for 50Hz has an inductance of 0.7H and a resistance of 3K ohm. Find the series resistance required to extend the range of instrument to 300V if this 300V - 50Hz instrument used to measure dc voltage find the dc voltage when the scale reading is 200V1.

Calculate and sketch its power output as a function of operating voltage and find its fill factor from this power output.Calculate the output power of solar PV system having three same size series connected PV Modules.

- A current of 10 A is passed through a 1-mm-diameter wire 1000 m long. Calculate the power loss if the wire is made from (a) aluminum and (b) silicon.About 20% of a home’s use of energy goes to lighting, while the number for commercial establishments is closer to 40%. Fluorescent lights are about four times more efficient than incandescent lights—this is true for both the long tubes and the compact fluorescent lights (CFL). Thus, a 60-W incandescent bulb can be replaced by a 15-W CFL, which has the same brightness and color. The heat transfer from these CFLs is less, and they last up to 10 times longer. New white LED lights (which are clusters of small LED bulbs) are even more efficient (twice that of CFLs) and last 5 times longer than CFLs. However, their cost is still high. If the cost of electricity in your area is P10 per kWh, what is the total cost (capital plus operation) of using a 60-W incandescent bulb for 1000 hours (the lifetime of that bulb) if the bulb cost P100? If we replace this bulb with a compact fluorescent light that provides the same light output, but at 1/4 the wattage, and which costs P20 but lasts 10 times…Below is the table of PV specifications of a standard commercial silicon PV. a) Calculate the efficiency of this PV module. b) Calculate the fill factor of this PV module. c) Estimate the number of solar cells included in this PV module. d) Draw a sketch explaining how the solar cells are connected in the PV module.
