RE: Electrical Tutorial || What is Circuit, Series circuit & Parallel Circuit.
Thank you very much for sharing such a nice tutorial post about series and parallel. Here you have shown two lights on and off with two circuit breakers which were connected in parallel. And in another connection you have shown two lights in series with one circuit breaker. Now my question is how many 60 watt lights can be run in series with 220 volt input voltage. I don't think more than two lights can be run in series with 220 volt input voltage. If three or four lights have to be lit in series then 440 volts will have to be applied, probably it is for the series line.
Thank you very much for reading my post. Actually 220 volts and 440 volts are completely different. You have to select the voltage supply depending on the load. If you give 440 volts supply instead of 220 supply, then the circuit will burn out or any accident may happen. This idea that you have to increase the voltage or give 440 volts supply to light multiple lights is wrong. If you want to light 3,4 bulbs in series, then you have to take high wattage lights. Remember that if you want to light 3,4 lights, then you have to use high wattage lights. I use here 200W light. Since the voltage is divided in series, the light of lights 3,4 will be very low and may not light in many cases. For this, you have to connect in a parallel circuit to light multiple lights.
A high-wattage bulb will produce some light even at low voltage. But a low-wattage bulb at low voltage is more likely to produce no light.
Thank you for your answer. As far as we all know, in parallel connection, all loads get the same voltage and this is the most practical way to light multiple lights. So if we connect four lights in series, each light will receive only 55V, so it will not light up or will give very little light. Thanks for your explanation, but one thing needs to be clarified here, is the wattage or voltage of the light important in series connection. If the sum of the rated voltage of each light is equal to the supply voltage, then I think all the lights will light up properly. So I think the real issue is not high wattage, but selecting the right voltage light.
Imran bro, if you supply 440 volt source voltage, you will have to install 440 volt lights. If you make series or parallel connections here, then 220 volts, you will have to install 220 volt lights. At 220 volts, you will get a two-wire connection. If you provide 440 volts, you will have to provide a three-phase connection. Is it possible to provide three-phase connection to the lights? I hope you understand.
I understood from the previous answer that multiple lights can be operated in parallel connection and multiple lights cannot be operated in series connection. The light may be dim or may not light up at all.
You are correct, if you connect 420 volts to light the lights, you need a three-phase line because there are no three-phase lights. So if you connect lights in series at 220 volts, it is probably not possible to run more than 2. The light will be dim or not light at all.
