All domestic equipment come with a standard voltage.,.In parallel circuit each equipment gets the same voltage.
So you have to connect them in parallel to work. IN series if one bulb gets fused the whole chain do not work.
All bulbs, fans,,other small equipment are connected in parallel.
One of the most important merit is that a parallel circuit has
This question should be categorized as physics rather than as earth science.
The most important merits of a parallel circuit are summerized in two ways.
(1) The voltage is constant for all resistors.
(2) Even if some parts of the circuit are unconnected, current keeps flowing through the other parts of the circuit.
Merit (2) has been already explained and visualized in chandramohanPanakkal's post. This article focuces on merit (1).
For example, supposing two electrical appliances
The current is calculated by
Their resistance is
Let's see what happens if
The total resistance would be
Therefore, the voltage on
Electrical appliances wouldn't work at the half voltage as had been expected!
On the other hand, if
