Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
2 Corinthians 9:7 NIV
- Electric charge (Wikipedia)
Electric charge (symbol q, sometimes Q) is a physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative. Like charges repel each other and unlike charges attract each other. An object with no net charge is referred to as electrically neutral. Early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
