. A battery charger meant for a series connection of ten nickel-cadmium batteries (total emf of 12.5 V DC) needs to have a 15.0 V output to charge the batteries. It uses a step-down transformer with a 200-loop primary and a 120 V input. (a) How many loops should there be in the secondary coil? (b) If the charging current is 16.0 A, what is the input current?

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)
