PhysicsSingle correct+4 / -1Question 38 of 90

The charge on capacitor of capacitance $15\ \mu F$ in the figure given below is :

60\ \mu

130\ \mu

260\ \mu

585\ \mu

Answer and worked solution

Official answer: A

Series. $\dfrac1C=\dfrac1{10}+\dfrac1{15}+\dfrac1{20}=\dfrac{13}{60}$ , so $C=\dfrac{60}{13}\ \mu$ F.

Charge (same on each in series): $Q=\dfrac{60}{13}\times13=60\ \mu$ C.

(A)

Topics:Series and parallel combinations
