Multimeter in a Bridge , physics?

Question

The multi-meter M is a multi-mode measuring instrument capable to measure either voltage or current depending on its mode switch. part 1
What is the magnitude of the voltage shown by the multi-meter, when it is set in the voltmeter mode. Use the following data: ε = 12.0, R1 = 12.1 Ω, R2 = 39.7 Ω, R3 = 37.5 Ω, R4 = 14.5 Ω.
5.85 V - ans
second part
What is the magnitude of the current shown by the multi-meter, when it is set in the ammeter mode. ?

Answer 1

All you did was list a bunch of components with no clue as to the circuit they're in.
