Study Notes

Electric Forces and Fields

  • If the distance between two charges is quadrupled, the force between them is reduced to one-sixteenth of its original value.

Electric Field Lines

  • Electric field lines due to charged particles always start from positive charges and end at negative charges.

Electric Field Intensity

  • If the distance from a point charge is doubled, the electric field intensity decreases to one-fourth of its original value.

Forces between Charged Bodies

  • Charged bodies exert forces on one another because they interact with each other through the electric field.

Capacitance

  • The correct unit of capacitance is the Farad (F).

Capacitors in Series

  • When three 15 μF capacitors are connected in series, the net capacitance is 5 μF.

Capacitors in Parallel

  • When three 10 μF capacitors are connected in parallel, the net capacitance is 30 μF.

Capacitive Circuits

  • Alternating current can flow in a capacitive circuit with AC voltage applied because the capacitor continuously charges and discharges.

Dielectric Materials

  • A common misconception about dielectric materials is that they are conductors, when in fact they are insulators that can be polarized by an electric field.

Parallel Plate Capacitors

  • When the plates of a parallel plate capacitor are separated, the voltage across the plates increases.
