2.Two resistors of X and Y are in parallel with one another and in series with a 200 O resistor and a battery whose emf is 1.5 volt and whose internal resistance is 0.5 O. The resistance of X is 100 O. When Y is disconnected from X, an additional resistance of 50 Ohms must be inserted in the circuit in order to keep the current through X is unchanged. Find the resistance of Y. Compute the value of Y again for the same case considering the internal resistance of the battery negligible.
