PHYS 242 BLOCK 1, PART 1, NOTES Sections 21.1 to 21.7 Objects may have a property calledelectric charge(usually just calledcharge) (TERM 1). The SI unit of electric charge is 1 coulomb = 1 C. (Electric ) current is the motion of (electric) charge (TERM 2). The SI unit of electric current is 1 ampere = 1 amp = 1 A. Then 1 C≡ 1 A·s (≡ is the mathematical symbol for “is defined to equal”). Charge can be either positive (+) or negative (–). Particle Charge (q) Rest Mass (m 0 TERM –19 –31 electron –e = –1.602 × 10 C 9.109 × 10 kg 3 proton +
