If you have a string of lights and one light goes out but others stay lit, which type of circuit do you have a) broken b) short c) series d) parallel

D) Parallel.

Explanation:

We know there  are two types of circuit:

1. Series

2. Parallel.

In series circuit , all the resistors are connected in a queue i.e. current will flow to another resistor only when it passed to the resistor before it.

In such cases fault in any one resistor cause circuit block to others too.

In parallel circuit , all the resistor are connected in parallel to each other i.e. all resistors between two points are connected to each wire. So, any fault in any one of resistor now cause others to run.

In such cases fault in any resistor do not cause circuit block.

As , it is given that one light goes out but others stay lit.

Therefore, it is PARALLEL connection.

weight is the answer i just took the test
