Find current and voltage using a schematic
I need to find current (labeled I) and voltage (labeled V).
I got I = 7.426 mA and V = 7.426V but I think it's wrong.
I know the formulas and all, but I just need to know how to combine the resistors (which ones are in parallel and which ones are in series?) I know that R3 and R4 are in series so I combine them and get 2k equivalent resistance. After that point, I don't know how to combine the rest of the resistors. Can someone help me out?
NOTE: I'm not asking anyone to do all the math and tell me the numbers!! I just want to know how to combine the rest of the resistors after R3 and R4 have been combined
R3 + R4 = 2k as you said. This is in parallel with R5. Find this value say R2L (2nd loop).shaqtus
I need to find current (labeled I) and voltage (labeled V). I got I = 7.426 mA and V = 7.426V but I think it's wrong.
R2L is in series with R2. Find the value. Say R2B (Second branch)
R2B is in parallel with R6. Find this value say R1L (first loop).
I = 5/(R1 + R1L)
Now for the voltages. You can easily find Voltage across R1L (R1 & R1L are in series). Say V1L.
V1L is across R2 + R2L. Find voltage across R2L. Say V2L.
V2L is across R3 and R4. It is easy now to get V.
There may be a simpler way. Perhaps the grey beards in electrical field may pitch in with a simpler solution.
shaqtusThanks. I got I = 0.0003A and V=0.635V . Could you please verify my work?
I get I =0.5849 ma and v = 172 mVshaqtusThanks. I got I = 0.0003A and V=0.635V . Could you please verify my work?
