Question 1 of 5
CBSE Past Year 2026

Assertion (A) : The work done, in taking a unit charge around a closed loop of an electric circuit involving cells and resistors in the loop, is zero.

Reason (R) : The potential at a point depends on the location of the point in the loop. After completing one round, the charge comes back to the point of start.

Question 4 of 5
CBSE Past Year 2026

Assertion (A): In a Wheatstone bridge circuit, if we interchange the position of the cell and the galvanometer, the balance condition \(\frac{P}{Q}=\frac{R}{S}\) remains unchanged.

Reason (R): \(\frac{P}{Q}=\frac{R}{S}\Rightarrow\frac{Q}{S}=\frac{P}{R}\) so balance condition remains same.
