263917 In a circuit shown in figure, if the internal resistances of the sources are negligible then at what value of R will the thermal power generated in it will be the maximum:

1 \(1 \Omega\)
2 \(2 \Omega\)
3 \(3 \Omega\)
4 \(4 \Omega\)

263918 A series combination of \(n_1\) capacitors, each of value \(\mathrm{C}_1\), is charged by a source of potential difference 4 V . When another parallel combination of \(\mathrm{n}_2\) capacitors, each of value \(\mathrm{C}_2\) is connected across potential difference of 4 V . it has the same (total) energy stored in it, as first combination has. The value of \(\mathrm{C}_2\) in terms of \(\mathrm{C}_1\) is then:

1 \(\frac{\mathrm{C}_1}{\Pi_1 \Pi_2}\)
2 \(\frac{16 \frac{\Pi_2}{n_1} C_1}{}\)
3 \(2 \frac{n_2}{6 n_1} c_1\)
4 \(\frac{16 \mathrm{C}_1}{\pi_1 n_2}\)
