voltmeter included in the network posldovatelno resistance R1, showed voltage 1 = 198, while the inclusion of series with the resistance R1 = 2P1-voltage 2 = 180B define the resistance R2 = 2P1-voltage network, if the resistance of the voltmeter r = 900m.

this physics i need help,,,,,,voltmeter included in the network  resistance R1, showed voltage 1 = 198, while the inclusion of series with the resistance R1 = 2P1-voltage 2 = 180B define the resistance R2 = 2P1-voltage network, if the resistance of the voltmeter r = 900m

radar · Answer

I believe this is a case where a diagram would be worth a thousand words.  I still can't envision this circuit.  I believe the internal resistance (impedance) of the voltmeter is 900 meg ohms (900m).  I just can't figure out the resistance arrangement or the voltage nodes?  Hopefully someone taking the same course can help you

gina · Answer

you are right but how do i get someone who is doing the same course

radar · Answer

What is the name of the course?

gina · Answer

physics electricity

radar · Answer

Is their a diagram for that problem?  Is there a way to upload the diagram?

gina · Answer

no i have no diagram it just like that what is important is the formula are shown

radar · Answer

How many resistors ( I am assuming two R1 and R2)  Are they connected in parallel or are they in series?

radar · Answer

What does resistance r1=2P1-voltage 2=180B........Resistance is usually in Ohms.  What is the B  ???

gina · Answer

resistance R1=2R1(that is resistance one is twice resistance two) and then V2 =180 IS the voltage in volts,so the (B) IS THE VOLTS cuz i had to translate into english from russian

radar · Answer

If the two resistors are in series, then the voltage across the largest resistor would be twice the voltage across the smaller resistor.  The voltage would be 60 volts, and 120 volts.  the internal resistance of the voltage meter would not have any signifacance bearing on your measurements since it has such a high value (900m).  Gina I am just speculating, as really don't understand the lay out!  I would try entering the problem again, maybe someone else can figure the circuit out.

gina · Answer

please if you cud show some work cuz the answer here z 220v but do not know how

radar · Answer

Sorry Gina, I can't figure how the answer is 220V.  I am missing a concept here.  Good luck with the problem, I would reenter it for answers.  Because now, it shows replies and others may not look at it.
