So You must have this question in your mind that Does Lightning and sound is produced at the same time or not because Lightning is seen Before we heard Thunder Sound .

So here is the answer to your question.. So as we know in series connection if we connect two appliances together then two or more appliances are connected from head to tail with each other which result in same current in both the appliances.

For example: if we connect one fan and one bulb together in series and if we switch ON both of them and somehow Fan do not work then the power will not transferred further and bulb will also not glow. But now in the case of parallel connection the appliances are joined parallely due to which the current are different in different branches according to the need of electrical appliances so if any appliances get failed then i...
