sieres and parallel circuits (+ LDR, theromister and LED)

define series circuit

where all components are connected in one big loop

key points of series circuits

current is same everywhere

voltage is shared equally

if one component breaks, the whole thing stops working.

Define parallel circuits

A circuit where components are in multiple branches.

key points of parallel circuits

if one path is brocken, other path will still work.

full voltage for each branch

current is splitted into each path.

Define LDR

(Light Dependant Diode) Resistor that changes due to the light level

bright light = low resistance

dim light = high resistance.

define theromister

Resistor that changes due to temperature

temperature increase = resistor decrease

temperature decrease = resistor increase.

Define LED

(Light Emmitting Diode) gives off light when current flows through it
