Find the current through the $10\Omega$ resistor shown in figure.
✓
Answer
In the circuit ADCBA, 
$3\text{i}+6\text{i}_1-4.5=0$
In the circuit GEFCG,$3\text{i}+6\text{i}_1=4.5$
$=10\text{i}-10\text{i}_1-6\text{i}_1=-3$
$\Rightarrow[10\text{i}+16\text{i}_1=-3]3\ ...(1)$
$[3\text{i}+6\text{i}_1=4.5]10\ ...(2)$ From (1) and (2)$-108\text{i}_1=-54$
$\Rightarrow\text{i}_1=\frac{54}{108}=\frac{1}{2}=0.5$
$3\text{i}+6\times\frac{1}{2}-4.5=0$
$3\text{i}-1.5=0\Rightarrow\text{i}=0.5$
Current through $10\Omega$ resistor = 0A.Need a full question paper?

A box of 1.00m3 is filled with nitrogen at 1.5 atm at 300K. The box has a hole of an area 0.010 mm2. How much time is required for the pressure to reduce by 0.10atm, if the pressure outside is 1atm.
A man walking briskly in rain with speed v must slant his umbrella forward making an angle $\theta$ with the vertical. A student derives the following relation between $\theta$ and v: $\tan \theta = \text{v}$ and checks that the relation has a correct limit: as $\text{v}\rightarrow 0,\ \theta \rightarrow0,$ as expected. (We are assuming there is no strong wind and that the rain falls vertically for a stationary man). Do you think this relation can be correct? If not, guess the correct relation.
