Parallel circuits can operate with either AC (alternating current) or DC (direct current).
In other words, being wired in parallel doesn't dictate whether a circuit uses AC or DC. The type of current used (AC or DC) depends on the source of the power, not how the components are connected.
Explanation
-
Parallel Circuit: A parallel circuit provides multiple paths for current to flow. Components are connected side-by-side rather than in a single line (as in a series circuit). If one component fails, the others can still function because the current can flow through the other paths.
-
AC (Alternating Current): The electric current periodically reverses direction. This is the type of electricity commonly supplied by power grids in homes and businesses.
-
DC (Direct Current): The electric current flows in only one direction. Batteries and solar cells typically provide DC power.
Examples
- AC in Parallel: The lights and appliances in your home are wired in parallel using AC power from the electrical grid.
- DC in Parallel: Some automotive lighting and accessories are wired in parallel using DC power from the car's battery.
Key Takeaway
The type of current (AC or DC) is independent of the wiring configuration (series or parallel). Parallel circuits can be powered by either AC or DC sources.
