21. Of the 200 is made up of the same sources of EMF battery so that there are n series-connected groups, each of which contains m sources connected in parallel. The internal resistance r1 of each of the elements is equal to 2 ohms. Battery is shorted to the external resistance R = 98 ohms. Determine the values of n and m, at which the current in the circuit is maximized.
