Question

Ans the star marked questions with reference to diagram

Answer 1

b) there are total 40 photovoltic cell

therefore, potential difference = 0.5V

for each cell is

for 40 cell = 40*0.5=20V

thereforethe potential difference for above combination cell is 20V

2.Photovoltic cell for 1cm^2 is 0.5V

therefore for 100cm^2 =100*0.5

=50V

therefore the potential difference is 50V because it incresed by 100cm^2

3. solar energy can be requied during day time and on connecting inverter it stores energy therefore to use the energy at any time at day or night
