- Charge: The property of matter that is responsible for electrical phenomena is called charge. The charge is of two- types positive and negative.
- Law of charge conservation: Charge is neither created nor destroyed; it can only be transferred from one system to another.
EXPLANATION:
- The total charge on the two spheres will be conserved by the law of charge conservation
- But energy may not conserve because if they are of a different size or have different charge then some of their energy might lose in the redistribution of charge.
- In the case of the final potential, it is not always the mean of original potential because during the redistribution of charge some losses occur, but final potential on both spheres is always equal.
- People mistakenly think that an object gets a positive charge by receiving extra positive charges, it losses negative charge (electrons) to become positive.
