2. Three resistors R1, R2 and R3 are connected in series parallel with R1 in series with parallel combination of R2 and R3. The whole combination is connected across a 120V DC source. Resistors R1, R2 and R3 takes 750 W, 250 W and 200 W, respectively. Calculate the resistance R2. Why are street lights connected in parallel and not in series, explain.

Please answer this question by explaining each sentence that mentioned in the paragraph. Some sentences can be seen as not requiring mathematical explanation, equation but in fact if it possible please explain the question by giving mathematical, theoretical explanation. If it possible explain the question step by step why you used that formula, calculation etc. Thanks in advance.   By the way, question is related with the communication systems (electrical electronic engineering lesson).
