152515 A carbon resistor of $(47 \pm 4.7) \mathrm{k} \Omega$ is to be marked with rings of different colours for its identification. The colour code sequence will be

152516 Two cells, having the same emf are connected in series through an external resistance $R$. Cells have internal resistances $r_{1}$ and $r_{2} \quad\left(r_{1}>\right.$ $\left.r_{2}\right)$ respectively. When the circuit is closed, the potential difference across the first cell is zero. The value of $R$ is

152517 The resistance of the platinum wire of a platinum resistance thermometer at the ice point is $5 \Omega$ and at steam point is $5.23 \Omega$. When the thermometer is inserted in a hot bath, the resistance of the platinum wire will be $5.795 \Omega$. Calculate the temperature of the bath.

152518 A resistance $R$ is connected to ' $n$ ' identical cells. If the current in the resistance is same whether the cells are connected either in series or in parallel, then the internal resistance $(r)$ of each cell is
