So, for example, if something contains 321 positive charges and 319 negative charges, the net charge is 321 – 319 = +2. If it contains 37 positive charges and 42 negative charges, the net charge is 37 – 42 = -5.

Webacquired a Net Charge. The Net Charge is determined by the excess or extra number of charges that it has gained/lost. We determine net charge in the following way: q = ne where q (could also be Q) represents the Net Charge, n is the extra number of protons/electrons, and e represents the "Elementary Charge"; the amount of charge of 1 p, or 1 e-. WebThe net final charge of the system is q final = + 10 C + q red, where q red is the final charge on the red sphere. Conservation of charge tells us that q initial = q final, so we can solve for q red . Discussion Like all conservation laws, conservation of charge is an accounting scheme that helps us keep track of electric charge. Practice Problems
