Answer:
The main advantage of burning biomass over burning of fossil fuels is that it is a renewable resource and cheaper than fossil fuels.
Explanation:
Biomass is a type of organic matter which is extracted from both plants and animals. It has a variety of uses and advantages such as it is cheaper source as compared to fossil fuel. It is available everywhere in large quantity. It also used for the production of heat and electricity. It is produces less pollution by producing less carbon dioxide gas as compared to fossil fuels which produces more carbon dioxide gas in the atmosphere.

yes it is because he had said there were thousands
Step-up transformer :
• Primary winding (Np) is smaller than secondary winding (Ns)
• Primary voltage (Vp) is smaller than secondary voltage (Vs).
• Primary current (Ip) is greater than secondary current (Is).
Step-down Transformer :
• Primary winding (Np) is greater than secondary winding (Ns)
• Primary voltage (Vp) is greater than secondary voltage (Vs).
• Primary current (Ip) is smaller than secondary current (Is).
So, the equation is :
Note :
Np = Primary winding
Ns = Secondary winding
Vp = Primary voltage
Vs = Secondary voltage
Ip = Primary current
Is = Primary current
