Hint:

Important associations in Renewable Energy Systems:
• Solar PV \(\rightarrow\) I-V Characteristics
• Wind Energy \(\rightarrow\) Betz Limit
• Hydro Power \(\rightarrow\) Spillways
• Biomass \(\rightarrow\) Digestion Processes

Answer 1

The Correct Option is B

Concept: This question is based on matching renewable energy technologies with their associated characteristics or concepts. Each renewable energy source has a unique operational principle and associated terminology.

Step 1: Match Biomass Energy
Biomass energy involves decomposition of organic matter such as:
• Agricultural waste
• Animal waste
• Plant residue One important process associated with biomass conversion is digestion. Aerobic digestion occurs in the presence of oxygen. Therefore: \[ A \rightarrow II \]

Step 2: Match Small Hydro Energy
Hydroelectric systems use water reservoirs and dams. A spillway is an important hydraulic structure used to:
• Release excess water safely
• Prevent dam overflow
• Protect the structure from damage Thus: \[ B \rightarrow IV \]

Step 3: Match Solar PV System
Photovoltaic systems are analyzed using current-voltage characteristics known as I-V characteristics. These curves help determine:
• Maximum power point
• Efficiency
• Voltage-current relation Hence: \[ C \rightarrow I \]

Step 4: Match Wind Power Plant
Betz’s limit defines the maximum theoretical efficiency of a wind turbine. It states that no turbine can capture more than: \[ 59.3% \] of kinetic energy in wind. Therefore: \[ D \rightarrow III \]

Step 5: Final Matching
Thus, the correct matching becomes: \[ A-II,\ B-IV,\ C-I,\ D-III \] Hence, the correct option is: \[ \boxed{(B)} \]
