Series Circuits

Learning the difference between Series and Parallel circuits is important. 

In series circuits, the components are added in 'series' or in one line, as if they were all on one wire. The thing about this type of circuit is that if the wires break, the whole circuit stops working.
This also means that the potential difference is shared throughout the circuit.

You might get an equation like this :
Vtotal = V1 + V2 + V3.

If we were to put a 12-volt cell or battery, and have two filament lamps on the circuit, both lamps have to add up to 12 volts

On the other hand, current is the same everywhere in the circuit. To measure it, we use ammeters, which are placed in series, and since they measure current, we can place them anywhere in the circuit.

Resistance is how much the component resists electricity, and the total resistance is how much all components resist, so to calculate the resistance in ohms, we need to know how much power our components resist. 

So, let's take a 6 ohm circuit and connect two filament lamps. One lamp requires 4 ohms, and the other requires 2 ohms.

To calculate this, we can use the equation "V=IR", which is named Ohm's law, the 'V' in the equation means voltage, so first we multiply the 6 ohms by 2 to get 12v or 12 volts, then we divide the 12 volts by 6 because that's how many ohms are flowing into the circuit, to get 2A or tao Ammeters 2, this whole thing calulsates the whole circuit, but that hapfpenss if you need to calculate a single compident. 

To get the resistance of a single component, get tww

Find a component, let's use a 2 ohms filament lamp, now to use Ohm's equation again, now we have to rearrange the equation to fit the problem by changing it to be 'I=V/R', so we calculate the voltage by getting the amount of power coming
