Which two resistors are connected in series with a cell of emf 2V and negligible internal resistance, a current of (2/5)A flows in the circuit. When the resistances are in parallel, the main current is (5/3)A. Calculate the resistances.

Two resistors are connected in series with 5V battery of negligible internal resistance. A current of 2 A flows through each resistor. If they are connected in parallel with the same battery a current of (25)/(3)A flows through combination. Calculate the value of each resistance.

When 2 equal resistances are connected in parallel to the poles of a cell of negligible internal resistance, the power developed is P. When the same resistances are connected in series across the same cell, the power developed is

Two resistors of 5 Omega and 10 Omega are connected in parallel with a cell of emf 3 V and internal resistacne 1 Omega. Calculate the current through each of the resistors.
