Hi,
I can't figure out how question 6 has to be calculated.
This is the link to the question
I started with calculating the total resistance and got 0.009 [A].
Then I tried to calculate the current through the 1k+1k5+690 resistors.
The answer I found was 0,0054 [A].
So I also know the current through resistor 4700 [O] -> 0,0036 [A].
By calculating the voltage over the resistor 250 [O] I got: 0,009*250=2,25 [V]
By calculating the voltage over resistor 690 [O] I got: 0,0054*690=3,726 [V].
Summing the last to Voltages, I get: 5,976 [V]
But the correct answer should be 6,148 Volt.
Does anyone know what I'm doing wrong?
Thanks in advanced.
