Coulomb’s Law

Coulomb's law states that the attraction or repulsion force between two charged things is proportional to the product of their charges and inversely proportional to the square of their distance. It has an effect along the line that connects the two-point charges.

You are working as an electrician in a large steel manufacturing plant, and you are in the process of doing preventive maintenance on a large DC generator. You have megged both the series and shunt field windings and found that each has over 10 M to ground. Your ohmmeter, however, indicates a resistance of 1.5 across terminals S1andS2. The ohmmeter indicates a resistance of 225 between terminals F1andF2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer.
Shown below is a typical setup for a solar battery system. Sun’s energy is converted to electricity using solar PV modules. To match the output voltage of the PV module to the battery's, a charge controller is used which is a DC-DC converter. The sun’s output power is given as 1000 W/m2. The solar module has a surface area of 1 m^2 with a conversion efficiency of 10%. A charge controller converts the 20V module voltage to 12V battery voltage, with an efficiency of 84% The battery is 12V with a capacity of 10Ah. Assuming the battery is half empty (or half full, depending on your personality) and the bulb is powered on, how long will it take for the battery to be fully charged? How long can the bulb be powered at night, assuming full battery when the sun goes down and that you can fully drain the battery? (answer in hours)
