Increasing the charge on the plates of a capacitor means
Q = CV, where C is decided only by the geometrical factors
In a parallel plate capacitor the potential difference of 150 V is maintained between the plates. If distance between the plates is 6 mm, what will be the electric field at points A and B?
Which of the following is a non polar dielectric?
Alcohol and HCl are polar molecules since they have a net dipole moment towards a particular direction. Both water and benzene are non-polar molecules. But water is a conductor of electricity, whereas benzene is a dielectric (insulator).
The distance between the plates of a capacitor is d. What will be the new capacitance if a metal plate of thickness d/2 is introduced between the plates without touching them
What will be the effect on capacitance, if the distance between the parallel plates reduced to one-third of its original value?
What should be the radius of an isolated spherical conductor so that it has a capacity of 2μF?
Capacitance of an isolated spherical conductor =4π€R , where €=permittivity of vacuum
Work done in placing a charge of 8 x 10-18 C on a condenser of capacity 100 microfarad is
Given, charge =q=8×10−18C and Capacitance =C=100μF
Here the work done is the energy stored in the capacitor. i.e,
Capacitor preferred when there is a high frequency in the circuits is ______
Mica capacitors are preferred for high frequency circuits because they have low ohmic losses and less reactance.
A capacitor stores 0.24 coulombs at 10 volts. Its capacitance is
Q = CV
Work done in charging a capacitor is stored in it in the form of electrostatic energy, given by
W = Energy stored in the capacitor
