Two capacitors of capacitances 1.0 microfarad and 2.0 microfarads are each charged by being connected across a 5.0-volt battery.
Svetach [21]

Answer:

1.67 V

Explanation:

Q = Capacitance

Q' = Capacitance after connecting in series

V = Voltage

V_t = Voltage of battery = 5 V

Q_1=C_1\times V_t\\\Rightarrow Q_1= 1\times 5=5\ \mu F

Q_2=C_2\times V_t\\\Rightarrow Q_2= 2\times 5=10\ \mu F

As the plates opposite charge are connected together they are in series

Q_1'=Q_2'=Q_t

\frac{1}{C_t}=\frac{1}{C_1}+\frac{1}{C_2}\\\Rightarrow \frac{1}{C_t}=\frac{1}{1}+\frac{1}{2}\\\Rightarrow \frac{1}{C_t}=\frac{3}{2}\\\Rightarrow C_t=\frac{2}{3}

Q_2'=C_tV_t\\\Rightarrow Q_2'=\frac{2}{3}\times 5\\\Rightarrow Q_2'=\frac{10}{3}\ \mu F

V_2=\frac{Q_2'}{C_2}\\\Rightarrow V_2=\frac{\frac{10}{3}}{2}\\\Rightarrow V_2=1.66\ V

The voltage across the 2 microfarad capacitor is 1.67 V
