Alternating Current (AC)

AC power, supplied by the electrical grid, flows in alternating directions. It’s perfect for:

Motors in moving heads
High-power components before conversion to DC
Efficient long-distance transmission

Direct Current (DC)

DC power flows in a single direction and is preferred for:

LEDs and microcontrollers
Battery-powered stage lights
Stable, low-noise operation

Feature	AC (Alternating Current)	DC (Direct Current)
Flow Direction	Alternates periodically	Constant, unidirectional
Voltage Stability	Varies in sinusoidal waveform	Steady and consistent
Transmission	Long-distance efficient	Less efficient over long distances
Storage	Not storable	Storable in batteries
Applications	Motors, grids, appliances	LEDs, control systems, battery lights
Conversion	Motors, grids, appliances	Needs inverters for AC use
