SERIES AND PARALLEL CIRCUIT EXPLANATION ON THE LAMP

 Series Series

               A series circuit is an electrical circuit whose components are arranged in a row through only one electric current. An example is a circuit that has two resistors, but there is only one wire line to conduct electricity as shown below. As well as a series circuit is a circuit in which there is only one path where the electric current flows from the source of the electric current. In a series, all lights are in sequence. In a series, if one lamp is turned off, the electricity will stop and all the lights will also turn off. This is because the circuit is not closed and electric current cannot flow.

            The advantage of a series circuit is the large amount of electric current that is not divided. However, the voltage or current is divided so that the lights in the series circuit are dimmer.

In a series circuit, the electric current that flows is the same for each element and is formulated by:

The total resistance of the resistor in a series circuit is the sum of each resistance which is formulated by:

1. Overload of series

The advantages of the series are as follows.

•          The number of conducting cables needed in the series circuit is less or saves cables.
•          Lower installation costs.
•          Even though the resistance on each load is not the same, the load still passes the same current.

2. Lack of series

The shortcomings of the series are as follows.

•          If one load breaks or goes out, the other load will also go out.
•          Lights that are connected in series cannot light up at the same time. This is because the voltage in each lamp varies, depending on the amount of resistance.

 

Parallel circuit

               A parallel circuit is an electrical circuit whose components are arranged parallel where there is more than one electric path (branched) in parallel. An example is a circuit that has two resistors where there is one cable line for each resistor as shown below. As well as parallel circuits are circuits arranged in branches, by having more than one path through which electric current flows from the source of the electric current. As a result, since an electric current has more than one path taken, the circuit can still function if one path is interrupted or turned off.

            Parallel circuits have the same voltage between the branches so that the lights in the parallel circuit are brighter. However, the current is different

           In accordance with Kirchoff's Law 1, the incoming electric current must be the same as the current out. So that in a parallel circuit the amount of current before entering the branch is the same as the current after leaving the branch and is formulated as:

              In accordance with Ohm's Law, the total resistance of the resistor in a parallel circuit is the sum of the inverse resistance of each component and is formulated by:

1. The advantages of parallel circuits

The advantages of parallel circuits are as follows.

•          All lights connected in parallel will light up equally.
•          If one lamp goes out, the other lamp will not be affected.

2. Weaknesses of parallel circuits

The weaknesses of parallel circuits are as follows.

•          More cables are required, 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.
