MCQ

Two identical bulbs are connected in parallel across an ideal source of emf $E$. The ammeter $A$ and voltmeter $V$ are ideal. If bulb $B_2$ gets fused, then

A
Reading of $A$ will increase but that of $V$ will remain same
B
Reading of $A$ will decrease but that of $V$ will increase
✓
Reading of $A$ will decrease but that of $V$ will remain same
D
Reading of $A$ will increase and reading of $V$ will also increase

✓

Answer

Correct option: C.

Reading of $A$ will decrease but that of $V$ will remain same

c
(c)

If $B_2$ gets fused, $R_{\text {net }}$ increases, $i$ decreases, but reading of $V$ remains same.
