Q4_Lesson 5 - Electric Potential of Conductors

Michael Faraday

great British scientist

1836, “Faraday’s cage.”

year when Michael Faraday conducted experiments that lead to the invention of the famed ___

“Faraday’s cage.”

This room, or “cage,” was completely wrapped in metal foil and permitted discharges of high voltages from an electrostatic generator activated outside the room.

electroscope

Faraday used an ___ to prove that no excess charge entered the cage’s walls and volume

conductor, conduction electrons

permits free electrons, also called ___, to freely move between and among atoms

scatters, reduced

Every time a conductor receives an excess charge, it ___ about the conducting material such that the totality of repulsive forces inside the conductor will be ___

electrostatic equilibrium

every time a conductor receives an excess charge, it scatters about the conducting material such that the totality of repulsive forces inside the conductor will be reduced

Electrostatic equilibrium

condition in which the excess charge inside a conducting material has “optimally distanced” itself to reduce the amount of repulsive forces

directed perpendicular

The first characteristic of conducting materials at electrostatic equilibrium is that the field and the conductor’s surface are ____rto each other

no

Under electrostatic equilibrium, the charges are distributed such that -___electric field is present inside the conducting material

polarization

separation between the equal and opposite electric charges

similar

the field outside the sphere is ___ to that of a single charged particle

0

the electric field within a conducting sphere is equivalent to _____
