I must find the voltage indicated by the voltmeter for the circuit below:
This how I solved and I want to be sure it's correct.
R2 || R1
I=E/(R1+R2||R1)=3.746 *10^-6 A
So the voltage indicated by the voltmeter is I*(R2||R1)=8.243 V
And, if the voltmeter is ideal, the voltage should be 7.5 V.
Did i make any mistakes???
And I want to ask you one more thing. I'm a bit confused about this circuit. I learned that when you want to use a voltmeter you put it in ||, but in this figure, it's considered to be in || with R1 and in fact it indicates the voltage PT2??? Can anybody help?
