## Homework Statement

initial problem: A 228 −Ω resistor and a 586 −Ω resistor are connected in series across a 90.0−V line.

A voltmeter connected across the 228 −Ω resistor reads 24.0 V . Find the voltmeter resistance.

For Req, i got Req=228R/(2+228), R being the resistance of the voltmeter.

But after that, I'm stuck. How do I find the necessary I(current) in order to calculate the R (resistance of voltmeter).?

## Homework Equations

V=IR

1/Req=1/R1 +1/R2
