Solar Powered Vehicles MCQ [Free PDF] – Objective Question Answer for Solar Powered Vehicles Quiz

11. Calculate the active power in a 315 F capacitor.

A. 45 W
B. 81 W
C. 0 W
D. 64 W

Answer: C

The capacitor is a linear element. It only absorbs reactive power and stores it in the form of oscillating energy. The voltage and current are 90° in phase in the case of the capacitor so the angle between V & I is 90°.

P = VIcos90° = 0 W.   

 

12. Calculate the frequency of the waveform v(t) = sin(πt+π÷4) + sin(πt+π÷74) + sin(πt+π÷56).

A. .1 Hz
B. .8 Hz
C. .5 Hz
D. .2 Hz

Answer: C

The fundamental time period of the sine wave is 2π. The time period of i(t) is L.C.M {2,2,2}=2 sec.

The frequency of the waveform is 1/2=.5 Hz. The time period is independent of phase shifting and time-shifting.   

 

13. The diode conducts only when current flows from anode to cathode.

A. True
B. False

Answer: A

A diode is a unidirectional device. It starts conduction when current flows from the cathode to the anode of the diode. It is a bipolar device.

 

14. Full form of EV is ____________

A. Energy voltage
B. Electric vehicles
C. Electric voltage
D. Energy vehicles

Answer: B

The full form of EV is Electric Vehicles. It uses an electric motor for the machine propulsion. It does not cause pollution as there is no tail-to-pipe emission.   

 

15. Full form of ICV is ____________

A. Internal combustion vehicles
B. Internet combustion vehicles
C. Internally combined vehicles
D. Internet combined vehicles

Answer: B

The full form of ICV is an Internal combustion vehicle. It requires fuel for propulsion. It consists of a piston attached to a cylinder chamber.   

 

16. A solar cell converts light energy into __________

A. Electrical energy
B. Thermal energy
C. Sound energy
D. Heat energy

Answer: A

A solar cell converts light energy into electrical energy. The light energy excites the electron of the solar cell which further flows in the circuit and constitutes the electric current.   

 

17. There are three types of solar cells.

A. True
B. False

Answer: A

There are three types of solar cells. Single crystal, polycrystal, and amorphous silicon cells are the major types of solar cells.   

 

18. Series and parallel combination of the solar cell is known as _________

A. Solar array
B. Solar light
C. Solar sight
D. Solar eye

Answer: A

Series and parallel combination of the solar cell is known as the Solar array. Shunt diodes are used to avoid the circulating current.   

 

19. Full form of FF in the solar field is ____________

A. Form factor
B. Fill factor
C. Face factor
D. Fire factor

Answer: B

FF stands for Fill factor. It is the ratio of the maximum obtainable power to the product of the open-circuit voltage and short circuit current.   

 

20. Calculate the Fill factor using the data: Pmax=15 W, Voc=18 V, Isc=4 A.

A. .65
B. .59
C. .20
D. .98

Answer: C

The fill factor is the ratio of the maximum obtainable power to the product of the open-circuit voltage and short circuit current.

F.F=Pmax÷(Voc×Isc)=15/72=.20.
