We are doing a project on electricity as year 8 students. We are going to attempt to make a light bulb in our own made up circuit light up with the power of some onions if possible. May someone please explain, in simple words and vocabulary, what an onion contains inside of it and how it manages to power a light bulb ?

the closer the planet is to the sun, the larger the gravity

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
