Solar cells convert: MCQ with Answer and Explanation

Solar cells convert:
A. Light energy to electrical energy
B. Chemical energy to electrical energy
C. Electrical energy to light energy
D. Thermal energy to electrical energy
Answer: Option A
Solution (By JKExamLibrary)
Solar cells (photovoltaic cells) convert light energy (photons) directly into electrical energy via the photovoltaic effect: photons excite electrons in semiconductor material, creating electron-hole pairs that generate voltage. This is distinct from solar thermal (light to heat to electricity) or batteries (chemical to electrical). Memory aid: 'Photo = light; voltaic = electricity'. This renewable energy application question tests knowledge of energy conversion principles, common in competitive exams. Always distinguish photovoltaic (direct light-electricity) from other solar technologies.

Question #1 Report Error
A ship floats because its density is
A. Equal to water
B. Greater than water
C. Less than water on average
D. Zero

Correct Answer: Option C


Explanation:
Ship is made of steel (density > water) but hollow shape makes average density (including air) less than water. Displaced water weight equals ship's weight, buoyancy holds it up.

Question #2 Report Error
A projectile is fired with velocity u at angle 45° with horizontal. Its time of flight is (g = 10 m/s²)
A. u/5
B. √2 u/5
C. u/5√2
D. √2 u/10

Correct Answer: Option D


Explanation:
T = 2u sinθ/g = 2u sin45°/10 = 2u(1/√2)/10 = √2 u/10. SSC often tests projectile basics.

Question #3 Report Error
The unit of electric power can be expressed as
A. Ohm × meter
B. Volt × ampere
C. Joule × second
D. Coulomb × volt

Correct Answer: Option B


Explanation:
P = V I, so watt = volt × ampere.
