Answer:
If one bulb goes out, other bulbs stays lit.
If there is break in one branch of the circuit, current can still flow through other branches.
Parallel circuits are simple to design and build.
Explanation:
In parallel circuits all the components and resistors are connected to common terminal or common supply.
So here if we disconnect one of the branch of the circuit then it will not affect the other branches of the circuit so it will not affect the current of other branches.
So here it is very easy to build a parallel circuit and if one of the branch of the circuit goes out then it will not affect the other branches.
