Question

Students A and B connect the two resistors $R_1$ and $R_2$ given to them in the manners shown below :
And then insert them at X and Y into the measuring circuit shown below :
we can say that

• A. both the students will determine the equivalent resistance of the series combination of $R_1$ and $R_2$.
• B. both the students will determine the equivalent resistance of the parallel combination of $R_1$ and $R_2$.
• C. Student A will determine the equivalent resistance of the series combination while student B will determine the equivalent resistance of the parallel combination of $R_1$ and $R_2$.
• D. Student A will determine the equivalent resistance of the parallel combination while student B will determine the equivalent resistance of the series combination of $R_1$ and $R_2$ .

Answer 1

The correct option is C Student A will determine the equivalent resistance of the series combination while student B will determine the equivalent resistance of the parallel combination of $R_1$ and $R_2$.

In given figure Student A connect terminal mark $b_1$ and $c_1$ that means student A connected both resistance in series and student A will able determine series equivalent of both resistance.

Student B connected $b_2$ and $c_2$ at same potential and we know that potential in parallel combination is same thats means Student B will be able to find parallel equivalent circuit resistance .

Option C is correct option.
