Question :3
Subhang, Class: 10th, Narayana iit olympiad
Can we store charge and use it like a battery afterwards?
Answer: Yes you can store the current in the form of A.C also but you can do it only a little in a capacitor. that's where we convert it to in the form of D.C and store it in a Batteries, though it is expensive. What to do in some particular needs we have to base on batteries only to storing purpose.
That's why solar power is expensive.
Other wise we can have so much of electrical energy from solar but the storing problem which is becoming expensive.
Any how we will discuss in one special session about all these areas.
