In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents
through each component.
If two or more components are connected in parallel they have the same potential difference (
voltage)
across their ends. The potential differences across
the components are the same in magnitude, and they also have identical
polarities. The same voltage is applicable to all circuit
components connected in parallel.
If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.
