Best ResponseYou've already chosen the best response.0If I'm reading this right, you have two resistors in series followed by three in parallel, with all the individual resistances known (2.5, 0.25, then 4, 5 and 2 ohms). Voltage is given, so the problem is to solve for the current? You need to find Req for the parallel resistors. The formula is: \[\frac{1}{R_{eq} }= \sum \frac{1}{R_i}\] Does this help?

Best ResponseYou've already chosen the best response.0{5240}+2.5 0.25=4.129ohm to find i2,i2=[(405)/{(405)+2}]*100/4.129=16.56(approx)

Best ResponseYou've already chosen the best response.0u can also use ORCAD to solve that!
