series and parallel circuits

series circuit

-resistors are wired one after another

-resistors all part of the SAME LOOP —> each experience the SAME AMOUNT of current

-if they all exist BETWEEN the terminals of the battery, meaning they SHARE the potential (voltage).

is the same

In a series, the current ____

add them up

decrease

In a series, when resistance increases, current will _____. (light gets dimmer)

greater

In a series, the larger the resistance, the ____ the amount of voltage lost across the resistor.

voltage drop

when charges USE ENERGY to get through the resistor, each individual resistor’s own individual potential voltage is called ____ ___

loops

In a parallel circuit, there are multiple ___

junctions

parallel circuits will all have some position where the current SPLITS and comes back TOGETHER

equal

In a parallel circuit, the current going IN to a junction will

always ____ the current going OUT of a junction.

reciprocals

in a parallel circuit, how do you find the total Resistance?
