Carbon Cycle Chemical Reactions Involved: Photosynthesis: Air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a by product. During photosynthesis plants use carbon dioxide and produce oxygen.
Similar to shore power for ships, a ground power unit (GPU) may be used to supply electric power for an aircraft on the ground, to sustain interior lighting, ventilation and other requirements before starting of the main engines or the aircraft auxiliary power unit (APU).
A relay module suitable for direct connection to an Arduino board. The module requires 5 V power supply. The input control signal is identified with an âSâ. The relay has one change-over contact. It is capable of switching resistive loads up to 10 A at 250 VAC and up to 10 A at 30 V maximum.
