Parallel Circuits

What is the Voltage in a Parallel Circuit?

A parallel circuit is shown below with three
branches and a different resistor in each branch.

The cell (the power supply) and each resistor
has a voltmeter connected across it.

It is found that 

1. The voltage in a parallel circuit
is the same for all branches.  V₁ = V₂ = V₃.

2. The voltage for each branch is the
same as the supply voltage.  V₁ = V₂ = V₃= V_sup.

Each component behaves
as if it is connected independently to the cell.
