What can be said about voltage in a parallel circuit?

In a parallel circuit, the voltage is the same across all components connected in the circuit. This means that each branch of the circuit experiences the full voltage provided by the power source. For example, if a battery supplies 12 volts, each branch of the parallel circuit will also have 12 volts across it.

This uniform voltage occurs because all components in a parallel arrangement share the same two nodes. As a result, regardless of the resistance of individual components in each branch, they all have the same potential difference across them, which is a fundamental characteristic of parallel circuits.

In contrast, if we consider the options where voltage varies, is greater in branches, or non-existent, those do not accurately describe the nature of voltage in a parallel circuit. Overall, understanding this concept is crucial for analyzing how parallel circuits function and how voltage behaves within them.
