Question

Name a conductor which can be given any amount of charge

Answer 1

Answer:

Earth can be given almost infinite charge since it has very large capacitance and can store large amount of charges.

Answer 2

Answer:

Is there any conductor which can be almost unlimited charge?

Not, a single conductor but a capacitor type set up and u can charge it as much as u want as long as your have it set up in environment which has high,very high breakdown voltage .

Use the formula to calculate voltage and capacitance for your unlimited charge.

I think the capacitance value will limit u so consider high voltage.

U could use van-de- graff generator or transformers etc for your high voltage requirement.
