Which of the following is an example of a series parallel-circuit. Correct Answer <img alt="F1 Shraddha Shubham 02.06.2021 D3" src="//storage.googleapis.com/tb-img/production/21/06/F1_Shraddha_Shubham_02.06.2021_D3.png">

Concept:

Parallel Circuit: 

When resistors are connected with several conducting paths between the sources of emf. In a parallel connection, the voltage remains the same across all resistors, but the current will be different.

R2 and R3 are connected from end to end so R2 and R3 are in series combination. their equivalent resistance is given as;

Req = R2 + R3

And, this combination is connected in parallel with R1.

Hence the given circuit is an example of a series-parallel circuit.

Option 2:

The voltage across R1 and R2 is V. Hence these are in parallel connection.

Option 4:

Resistance R1 and R2 are connected in series.
