Question

Why are the electric appliances in the household electric circuits (instruments) connected in parallel combination?

Answer 1

Hint: Here we have to go through the properties of parallel combination and the series combination then think about which connections are used in our household appliances.

Complete Step-by-Step solution:
There are a lot of electrical devices in a house that have to operate separately from one another. When one appliance is switched on or off, then the other devices will not be affected. It is not feasible if all the devices were connected in a series arrangement because there would be one switch that either turns on or off all of them.
If devices are attached in a parallel arrangement, each can be autonomously turned on and off. It is a function important in the cabling of a home.
Additionally, if the appliances were wired in series the possible difference would vary through each appliance depending on the appliance's resistance. It would make supplying the right power to flow through the equipment very difficult. This problem does not arise when house cabling is done in parallel, as the potential difference across each appliance is the same and equal to the potential difference the power company provides.

Note: Whenever we face such a type of question the key concept for solving the question is to study properly the properties of parallel combination and series combination and then learn what are these advantages and disadvantages and where we have to apply these combinations.
