How can biomass create electricity?
Most electricity generated from biomass is produced by direct combustion. Biomass is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity.
Where is the electric field zero between two positive charges?
There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the “outside” of the smaller magnitude charge.
How electrical signal is converted into optical signal?
An optical transmitter takes the incoming electrical signal and converts it into an equivalent light signal. This process is accomplished by means of Light Amplification by Stimulated Emission of Radiation (or laser). … Each optical signal has its own wavelength or frequency.
