In the given circuit, find the charge flown through the switch ( in micro coulomb) from A to B when it is closed.

Answer:

Solution:

lnitially

finally

$(V + 8) \times 3 + 3 (V - 0) + (V - 0) \times 3 + (V + 6) 6 = 0$

$15 V + 60 = 0$

$∴ V = - 4 V$

Net charge on system ABD

$Σ q = - 96 - 12 + 3 \times 4 = 96 μ C$
