Electricity & Magnetism

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

Electricity terms

Charge – the cause of the Fe

Magnetism caused by moving charge – demo. Electric field/Magnetic field – demo.
