What is the characteristic of voltage in a parallel circuit?

In a parallel circuit, one of the defining characteristics is that the voltage across all branches is equal to the source voltage. This means that if you have multiple components connected in parallel, each component will experience the same voltage level as the power supply.

For example, if a parallel circuit is connected to a 12-volt battery, every branch will have 12 volts across it, regardless of the number of branches or the impedance of each branch. This uniformity in voltage is a critical aspect of parallel circuits that allows them to function correctly, enabling each branch to operate independently at the same voltage level.

This principle of equal voltage is particularly important for ensuring that devices in a parallel circuit can operate safely and effectively without affecting one another's performance.
