Question

Six billion electrons are detached from a pith ball. What is the charge on the pith ball in
Nanocoulomb? (1 billion 109 one nano =
10-°)​

Answer 1

Explanation:

When you deal with static electricity buildup, right away you will see the importance of and difference between each of the following concepts:

coulomb — Equivalent to the charge of about 6.242×10^18 (1.036×10^−5 mole) protons, and −1 C is the charge of about 6.242×10^18 electrons.

ampere — Used for current in a wire, independent of voltage. 1 coulomb of charge passing a given point in 1 second. An average lightning bolt contains 10,000 to 200,000 amperes of current.

farad — Used for capacitors in electronic equipment. One farad is defined as the capacitance across which, when charged with one coulomb, there is a potential difference of one volt. Likewise, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt. A farad is a lot; usually we use between picofarads to millifarads.
