This is bit tricky and may sound weird but somehow I have tried to express my doubt..
While I was reading the work done by capacitor in Wikipedia, i came across an eqn
dW = (q/C)dq followed by the statement
"Moving a small element of charge dq from one plate to the other against the potential difference V = q/C requires the work dW"
Now my question is why do we introduce the term dW instead of just W.
If u tel me" because it is small element of charge, and so we introduce the dq n dW term instead of q or W", then does it mean it is not applicable for large element.
What is the need to integrate this eqn in order to get the value for W.
I have come across many such terms in electronics where we introduce this derivative d term signifying its a small element.. but why it has to be like that and not the normal conventional symbol...
