plz help look at pic
If 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?
how is will be the result
Do I have the correct numbers? Is it 4 or 40?
{5||2||40}+2.5 0.25=4.129ohm to find i2,i2=[(40||5)/{(40||5)+2}]*100/4.129=16.56(approx)
@moha_10 hi check that lesson for better understanding of resistors in parallel http://utwired.engr.utexas.edu/rgd1/lesson05.cfm
u can also use ORCAD to solve that!
