Homework Statement
We are supposed to figure out the voltages over every resistance when measuring with a voltmeter
Homework Equations
R1=R2=10k ohm
R3=R4=100k ohm
R5=R6=1M ohm
R7=R8=4.7M ohm
U=10V
The Attempt at a Solution
The thing I'm not quite understanding is whether the resistors are in series ( meaning R1 and R2 and etc) or/and parallel. I tried using voltage division over the resistors and realized they would have same voltage over them, 5V, which is wrong, I think.
V1=U*((R1)/(R1+R2))=U*(R/2R)=U/2=5V,
One second thing we should take account is there is an internal resistance when measuring the voltages with a voltmeter, which is parallel to the measuring object. The internal resistance is usually 10M ohm or higher. How should I do now?
