A network of resistors is connected across a \(10~\text{V}\) battery with an internal resistance of \(1~\Omega\) as shown in the circuit diagram. The equivalent resistance of the circuit is:
1. \(\frac{17}{3}~\Omega\)
2. \(\frac{14}{3}~\Omega\)
3. \(\frac{12}{7}~\Omega\)
4. \(\frac{14}{7}~\Omega\)
The value of resistance for the colour code of the given resistor is:
1. \((36\pm36)~k\Omega~\)
2. \((470\pm47)~k\Omega~\)
3. \((360\pm36)~k\Omega~\)
4. \((360\pm18)~k\Omega~\)
In a meter bridge experiment, the null point is at a distance of \(30~\text{cm}\) from \(\mathrm{A}\). If a resistance of \(16~\Omega\) is connected in parallel with resistance \(Y\), the null point occurs at \(50~\text{cm}\) from \(\mathrm{A}\). The value of the resistance \(Y\) is:
1. \(\frac{112}{3}~\Omega\)
2. \(\frac{40}{3}~\Omega\)
3. \(\frac{64}{3}~\Omega\)
4. \(\frac{48}{3}~\Omega\)
