Current is in phase with voltage in series. What about in parallel?
An AC parallel circuit is a type of electrical circuit that consists of multiple branches connected in parallel, with each branch having its own components such as resistors, capacitors, and inductors. The circuit allows for multiple paths for the flow of alternating current (AC) from the power source.
In a series circuit, the components are connected in a single path, whereas in a parallel circuit, the components are connected in multiple branches. In a parallel circuit, the voltage across each branch is the same, while the current through each branch may vary. In contrast, in a series circuit, the current through each component is the same, while the voltage across each component may vary.
In an AC parallel circuit, current is said to be in-phase with voltage when both the current and voltage reach their maximum and minimum values at the same time. This is due to the fact that the voltage and current in a parallel circuit have the same frequency and are in sync with each other.
The total current in an AC parallel circuit is calculated by adding up the individual currents in each branch. This can be done using Kirchhoff's Current Law, which states that the total current entering a junction is equal to the total current leaving the junction.
One advantage of using an AC parallel circuit is that it allows for more efficient use of power, as the current is divided among multiple branches. Additionally, if one branch in the circuit fails, the other branches can still function. This makes AC parallel circuits more reliable than series circuits.
