Interpretation: It should be determined for the following lighting source is the most energy efficient.
Concept Introduction:
Light-emitting diodes:
The light emitting diode is a P-N junction diode. It is a special doped diode and mad e up of a special type of semiconductors. When the light emits in the forward biased, then it is called as a light emitting diode.
The light emitting diode is a two – led semiconductor light source.
Nick Holonyak invented the idea of light emitting diode, and he was working for the general electric company.
The LED is a special type of diode and they have similar electrical characteristic of a PN junction diode.
Hence the LED allows the flow of current in the forward direction and blocks the current in the reverse direction.
Nonrenewable sources are those for which the energy source is used and not concurrently replenished.
Renewable energy sources:
The sun energy is an example of renewable resources.
These include solar energy and energy derived from wind, biomass, and moving water likewise geothermal energy is a renewable resources.

Chemistry & Chemical Reactivity
- Nucleophilic Aromatic Substitution: What is the product of the reaction? *see imagearrow_forwardShow the correct sequence to connect the reagent to product. * see imagearrow_forwardThe answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forward
- Draw the Birch Reduction for this aromatic compound and include electron withdrawing groups and electron donating groups. *See attachedarrow_forwardShow the correct sequence to connect the reagent to product. * see imagearrow_forwardBlocking Group are use to put 2 large sterically repulsive group ortho.
