Question

A mark on the V & I curve of a solar cell having maximum value of V x I is called....... (a)maximum voltage point (b)maximum current point (c)wattage of solar cell (d)maximum power point

Answer 1

answer : (d) maximum power point .

explanation :- we know, power is energy consumed per unit time.
power = energy/time

energy = VIt
where t is time taken, V is voltage and I is current.

so, Power = VIt/t = VI

hence, V × I is called maximum power point.
