Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

6.The dielectric constant (relative permittivity) of glass is given by

0.1 to 0.4
0.5 to 1.0
2.0 to 4.0
5 to 100

7.A mica capacitor and a ceramic capacitor both have the same physical dimensions. Which will have more value of capacitance ?

Ceramic capacitor
Mica capacitor
Both will have identical value of capacitance
It depends on applied voltage

8.Which of the following material has least value of dielectric constant ?


9.Which of the following statements is incorrect ?

The thinner the dielectric, the more the capacitance and the lower the voltage breakdown rating for a capacitor .
A six dot mica capacitor colour coded white, green, black, red and yellow has the capacitance value of 500 pF
Capacitors in series provide less capacitance but a higher voltage breakdown rating for the combina�tion
A capacitor can store charge be�cause it has a dielectric between two conductors

10.For closer tolerances which of the following capacitors is usually preferred ?

Paper capacitor
Mica capacitor
Ceramic disc capacitor
None of the above
