Voltage across components in a parallel circuit

The voltage across components in parallel is the same for each component.

Question

Look at the parallel circuit below

A circuit with an open switch at the top left of the main circuit. At the left hand side is a 6 V battery. A wire circumvents the battery and has a voltmeter Vs labelled 1. On the bottom of the main circuit is one resistors at 100 ohms. A wire circumvents this and has a voltmeter V2 and is labelled 3. A wire connects the left hand side of the circuit to the right hand side. On this wire is a resistor at 100 ohms. A wire circumvents it and has a voltmeter V1 labelled 2.

What is the reading at:

1) Position 1: \(0 V\), \(3 V\) or \(6 V\)

2) Position 2: \(0 V\), \(3 V\) or \(6 V\)

3) Position 3: \(0 V\), \(3 V\) or \(6 V\)
