Study Notes
Charges
Positive Charge
- A positive charge is a type of electric charge that has the opposite polarity of an electron.
- It is denoted by the symbol "+".
- Positive charges are carried by protons, which are found in the nucleus of an atom.
- Positive charges are attracted to negative charges.
- Like charges (two positive charges) repel each other.
Negative Charge
- A negative charge is a type of electric charge that has the same polarity as an electron.
- It is denoted by the symbol "-".
- Negative charges are carried by electrons, which orbit the nucleus of an atom.
- Negative charges are attracted to positive charges.
- Like charges (two negative charges) repel each other.
- The negative charge of an electron is equal in magnitude to the positive charge of a proton.
