Задача 30563.

Two groups of three series-connected elements are connected in parallel. The emf of each element is 1.2 V, internal resistance r = 0.2 Ohm. The resulting battery is closed to an external resistance R = 1.5 Ohm. Determine the current strength in the external circuit and the efficiency of the battery.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
