Presentation Transcript

  1. Electricity & Magnetism

  2. Electricity terms • Charge – coulombs (Q) • Charge of an e- & p+ = 1.6 x 10-19 coulombs • Fe = KQ1Q2/r2 (Coulombs Law) • Current (I) – amperes (amps) = I = Q/sec. • Resistance (R) – resistance to the flow of e-s • Voltage – volts – V = IR • Power – watts - P = VI • Conductors & insulators • Capacitance – pulses of electricity

  3. Electricity & magnetism • Charge – the cause of the Fe • Magnetism caused by moving charge – demo. • Electric field/Magnetic field – demo.

  4. Circuit diagrams & symbols • See p. 597 of your text
