series and parallel circuits

  

In the picture above, you can see an electrical circuit arranged in series. A series circuit is an electrical circuit whose resistance is arranged side by side. In a series circuit, the strong current (I) will flow from the energy source (battery) from one resistance to another through one cable.

the series circuit has advantages in its use, namely the number of conducting cables needed is less or saves cables. and lower installation costs. Even though the resistance on each load is not the same, the load still passes the same current.

then the disadvantage of a series circuit is that if one load breaks or goes out, then the other load will go out too. Lights that are arranged in series cannot light up equally brightly. This is because the voltage in each lamp varies, depending on the amount of resistance.

in a case if we want to know how much current flows in the series above. and all we know is the resistance of each lamp for example 8 ohms with a total voltage of 24 volts. we only need to use the formula I = V / R we already know the total V and to find R total we only need to add up all the resistance of each lamp R = 8 + 8 + 8 so R = 24 volts so that if it is entered into the formula I = 24 / 24 so the current flowing in the circuit is I = 1 Ampere

In the picture above, you can see an electrical circuit arranged in parallel. A parallel circuit is a circuit in which all components or electrical loads are arranged in a row. Thus, the input from each load comes from the same source.

In its use, a parallel circuit has several advantages, namely that when it is on, all lights connected in parallel will have the same light level. and if one of the lights goes out, the other lights will not be affected exactly like the picture above, the third lamp goes out because the switch is turned off but the other 2 lights remain on.

There are also drawbacks in parallel circuits namely. The cable needed in a lot more, so the cost required is greater than the installation of a series circuit. The amount of current flowing in each load is not the same, depending on the amount of resistance on the load. So suppose we want to know the current flowing in the lamp, for example lamp 1 = 4 ohms lamp 2 = 12 ohms lamp 3 = 6 ohms with a total V of 24 volts, 1 / R = 1/4 + 1/12 + 1/6 = 2 ohms then we enter into the formula I = 24/2 so the total current is 12 amperes but each lamp has a different current according to its resistance lamp 1 (I = 24/4) = 6 A lamp 2 (I = 24/12) = 2 A lamp 3 (I = 24/6) = 4 A so according to the current obtained at the beginning the total current flows is 12 Ampere.

so the two images above are examples of series and parallel series, each of which has its own advantages and disadvantages, but for both of them it can be combined into a mixed circuit so that each other can bring out the advantages and cover the disadvantages of each circuit model.
