Question 1 of 5
1. Question
Consider the following statements about Diodes
- A diode is an electronic component which has two points of contact called its anode and cathode.
- A diode’s primary purpose is to allow current to flow in only one direction.
- An LED is a semiconductor device which emits light when electric current flows through it.
How many of the statements given above are correct?
Correct
Solution (c)
Statement Analysis
Statement 1 Statement 2 Statement 3 Correct Correct Correct · A diode is an electronic component which has two points of contact, or terminals, called its anode and cathode. Advantages of LED
· Energy Efficiency: It requires far less electricity to produce the same light as incandescent bulbs. LEDs use approximately 75-80% less energy than traditional incandescent bulbs
· Durability: LED bulbs are highly durable and resistant to shocks, vibrations, and temperature fluctuations.
· Instant Illumination: It provides instant illumination without the warm-up period required by incandescent bulbs.
· Heat Generation: LED bulbs generate very little heat, making them safer to handle and more efficient in terms of energy utilization.
· Environmental Impact: LEDs have a significantly lower environmental impact compared to incandescent. The energy efficiency and longer lifespan result in reduced greenhouse gas emissions and less waste
· A diode’s primary purpose is to allow current to flow in only one direction. · An LED is a semiconductor device which emits light when electric current flows through it. · It can produce all three primary colours – red, green, and blue – different LEDs can be combined on a display board to produce a large variety of colours. LEDs have several applications in industry, consumer electronics, and household appliances: from smartphones to TV screens, from signboards to ‘feeding’ plants light in greenhouses, from barcode scanners to monitoring air quality.
Context: Light-emitting diodes (LEDs) succeed the incandescent bulbs and fluorescent lamps of previous centuries as the world’s light-source of choice.

· The funds released under the Scheme are non-lapsable, i.e., the entitlement of funds not released in a particular year is carried forward to the subsequent years, subject to eligibility. · At present, the annual entitlement per MP/ constituency is 5 crore rupees.
· The role of the Members of Parliament is limited to recommend works. Thereafter, it is the responsibility of the district authority to sanction, execute and complete the works recommended within the stipulated time period.
· The elected Lok Sabha Members can recommend works in their respective constituencies. · The elected members of the Rajya Sabha can recommend works anywhere in the state from which they are elected.
· Nominated Members of the Parliament can recommend works for implementation, anywhere in the country.
· MPLADS works can be implemented in areas affected by natural calamities like floods, cyclone, hailstorm, avalanche, cloudburst, pest attack, landslides, tornado, earthquake, drought, tsunami, fire and biological, chemical, radiological hazards, etc.
· In order to accord special attention to the development of areas inhabited by Scheduled Castes (SCs) and Scheduled Tribes (STs), 15 per cent of MPLADS funds are to be utilized for areas inhabited by SC population and 7.5 per cent for areas inhabited by ST population.

· They speak a Dravidian language called Kolami, and nearly all of the adults also speak Marathi, Telugu, or Gondi.
· They also speak other languages like Marathi, Telugu or Gondi.
· For writing, this Kolma tribal community uses the famous Devnagari script.
