If using the same value resistors then the equation is simple value of one resistor / number of resistors e.g. In parallel the value of resistors decrease the more you add.
Breadboard basics for absolute beginners series#
For resistors in series their values always add, meaning 2 100ohm resistors in series would give a total resistance of 200 ohm however in parallel this is not the case. i have some 100ohm resistors lying around that will be perfect for this project. if this made no sense dont worry, i will go into more detail later.įor the purpose of this instructable i will only be connecting one led to a 6v source and use resistors to protect the led from burning up. so as two colums are needed to accommodate any component with two legs in parallel these components would share the same columns but be in separate holes. A parallel circuit in this would be that the components you desire to be in parallel would touch at the same polarity (-ve leg to -ve and +ve leg to +ve). The green lines in the image below form a series circuit where every component touches at different polarities (-ve leg of one component to +ve leg of another).
This would complete the circuit allowing current to flow from one side of the power source to the other through the led.

if for instance i wanted to put an led in this circuit by its self i would insert one leg into a free hole of the column where the black (-ve) power jumper is and the other in a free hole of the column that the red wire (+ve) is in. a circuit is completed when all the desired strips form a loop and are all connected sequentially. the power strips go horizontally in 5's where as the component strips go vertically also in 5's. as you can see i edited the picture below to give you an idea of how circuits are completed. The 2 rows of holes at either end are for power one for positive (red) one for negative (black). As you can see from the image below a breadboard has lots of holes, this may seem confusing at first but it really isnt.
