For the given circuit, R1=100 [W], R2=400[W], R3=[W], and R4=300[W]. Between points 3 and 4 in the circuit the voltmeter is connected and measures potential v34=10[V]. The resistivity of the meter, Rv is such that during the measurements maximum power transfer occurs between the circuit to the meter.
Find:
Voltage between points 3 and 4 before the voltmeter was connected.
