Current electricity

Conductor

a material allowing currents to flow through it easily

Insulators

materials that do not normally allow a current to pass through them, such as plastic and rubber

Current electricity

electricity made up of net charges in motion aroud a circuit

Simple circuit components

energy source, load/energy user (resistance), wires, switch

Electric current

moving charges, measured in Ampere

Ammeters

measure currents in ampere by being placed directly in their path

Movement of electricity

from negative terminal to positive terminal of voltage source

Voltage

a measure of available energy to push charges around a circuit, and the amount of energy released by an energy user

Series circuit

two globes are arranged one after another, meaning voltage is shared between the two, but current is not, if one blows the cicuit breaks

Parallel circuits

globes are arranged on seperate branches, one globe doesn’t break the other, voltage is the same, but current is shared

Power

the rate at which work is done, how much energy is transferred a second, measured in Watts (joules/second)

Energy

measured in watt hours
