Chem & Phys lesson 12

study notes

The field around electrically charged objects

Electrical field

Potential energy

Electrostatic energy (static electricity)

a gadget that can discharge static electricity when needed.

capacitors

a stream of electrical energy that flows without stopping

current

protective shield against the flow of electrons.

Insulator

a flow of electricity through a conductor

electric current

a circular path that starts and finishes at the same place.

circuit

power plants, power lines, and transformers.

electric grid

electricity produced by anything with a motor

alternating currents (AC)

when electricity goes through the shorter path

short circuit

the object we are trying to turn on

load

any device that slows down the flow of electricity through a circuit

resistor

a combination of different items that conduct electricity

battery

when a current flows only in one direction

direct current (DC)

measure the energy of the electrical charge

volts

devices we use to open and close circuits

switches

circuit with more than 1 resistor

series circuit
