Physics - Current Electricity Question with Solution | TestHub

⟶ Volt meter is ideal so negligible current will flow in volt meter so current in ${\mathrm{R}}^{\prime }$ is non zero.

→ Reading of Ameter $\mathrm{i}=\frac{2.5}{5+20}=0.1\mathrm{A}$

→ Charge on capacitor $\mathrm{q}=\mathrm{CV}$ $\mathrm{q}=2\times 0.1\times 20=4\mu \mathrm{C}$

at steandy state current is in the ammeter because of capacitor same as negligible current will flow in ${\mathrm{R}}^{\prime }$ Reading of volt meter is 2 V

Charge of capacitor $=2\times (3-1)=2\mu \mathrm{C}$

Reading of ameter $=\frac{2-1}{10}=\frac{1}{10}=0.1\mathrm{A}$ $\mathrm{i}=\frac{\frac{14}{140}}{140}=0.1\mathrm{A}$

Reading of voltmeter $=2-0.1\times 20+2-0.1\times 20=0\mathrm{V}$
