Open Question: What is the current of the 25ohms resistor?
Home >All Categories > Science & Mathematics >Physics >Open Question
Bozhena Member since:April 21, 2011Total points:95 (Level 1)Three resistors, of 40 ohms, 60 ohms, and 120 ohms, are connected in parallel, and this parallel group is connected in series with 15 ohms in series with 25 ohms. The whole system is then connected to a 120-V source. Determine (a) the current in the 25 ohms, (b) the potential drop across the parallel group, (c) the potential drop across the 25 ohms, (d) the current in the 60 ohms, (e) the current in the 40 ohms.Answer QuestionBe the first to answer this question.
