How to wire lamps in series and parallel with it's advantage and dis-advantage?

By Bharat Ribadiya -
Series connection of lamp

 These all lamps are connected in series. Each lamp is connected to the next one. The flowing current is same in all lamps but the voltage is different.
Good To know: This is not a suitable wiring for home Because the effect will be that two or more lamps will be glow dim, and removing one lamp will cause others to go out. Recommended lighting method for home and buildings on lighting points is parallel wiring circuit of lighting.

Advantage:

-Less size of wire cable is required in this type of wiring.

Disadvantages:

-The failure or removal of any single lamp will break the circuit and cause all of the others lamps to stop working.

-High supply voltage is required. As more lamps are added, they will all are glow dim and dim because the voltage is shared in the series circuit.

Parallel connection of lamp

These all lamps are connected in Parallel. Each lamp is connected between phase L and Neutral N.
In this circuit, adding or removing one lamp has no effect on the others lamps. This is just because of the Voltage in parallel circuit is same. Here, current is different. It is possible to add any number of lamps in the circuit, simply by extending the L and N conductors to other lamps.

Advantages:

-Removal of any lamp or breaking in the cable will not break the circuit, in other words, other lamps will still work and glow.

-As more lamps are added, they  not reduced in brightness.

Disadvantages:

-More cable wire is used in parallel lighting circuit wiring as compare to series connection.

In this article we learn about how to control a lamp with 3 different switches at different places. This is very useful. For doing this we required two 2-way switch, 1 intermediate switch and a lamp. Connect all these as shown as in the below diagram. Fig.-1 In the above diagram the lamp is on because the circuit is in closed condition.To understand easily the circuit diagram for this, is given below.  Fig.-2 In this case the lamp(bulb) is in off condition. So, the circuit is open condition. Here, one more example is given.  How you can turn on/off a lamp or bulb from six different places. For this we required four number of intermediate switch, two number of 2 way SPDT switch and 1 bulb. Connect all these components as shown as in the figure below. Fig.-3 What is Intermediate switch , its construction and working principle? Fig.-4 An intermediate switch have four terminals. Because of this terminals it is possible to change the flow of the current fro

In this article you will learn about how to do three phase wiring in home. Generally, the elctrical supply provider company install single phase energy meter for where requirements is 7.5 kW load in domestic areas but if this limit exceeded then they install 3-phase meter. For this we required following things. Requirements- Required Materials Number Three phase energy meter 1 Three pole, 63 A, MCCB 1 Double pole, 63 A, 30 mA, Trip current RCD 3 Double Pole MCBs, 63A 3 Single Pole, 20A, MCB 6 Single Pole, 16A, MCB 3 Single Pole, 10A, MCB 6 Distribution board cases 3 Cupper strips for MCB Common connection 3 Here, the connected load is single phase. their is no 3 phase load connected to the 3 phase system. The 3 phase wiring are used because our load is more then 7.5 kW. Now, let's start the procedure how to install 3 phase wiring for your home. Figure 1- 3 phase winding in home As shown in the

Automatic UPS system wiring for home or office This article is about how to connect a UPS system in our home or office and this is very useful information.  The below circuit diagram shows the how to connect a UPS from our main supply to appliance(load). This circuit diagram is for in case of falling the main power supply and you want to supply power to specific appliances, TV, AC, laptop etc. in your home or office.  As shown as, two rooms are connected with main power supply.  Here, you don't have to connect the neutral wire connection from UPS because it's already connected the phase and neutral wire from the main power supply with the same point. To connect UPS first you have to remove the connection of phase wire from the main distribution box(from SP,DP or CB) of those rooms which you want to connect with UPS. By doing this(connect with both supply), we can use the power without interruption. If main power fails the UPS will provides the power to the
