The thunderclouds are charged by friction between
The capacitance of a capacitor is 100μ F and the potential difference between plates is 50 volts then charge stored on each plate is
A capacitor holds 0.03 C of charge when fully charged by a 6V battery. To hold 2C of charge, the voltage required would be
To distinguish between insulators and conductors, we can use
On a dry day if we walk in a carpeted room and then touch some conductor we will fell
The ability of a capacitor to store charge is
The region around a charge q in which it exerts a force on a test charge is called
SI unit of capacitance is
The strength of an electric field at any point in space is known as
Paper capacitor and mica capacitor are the examples of
The electrostatic force acting on two charges of 1C separated by 1m is about
3 capacitors with capacitances 5µF, 6µF and 7µF are arranged in parallel combination with a battery of 5V, as 1µF = 10-6F, the total capacitance should be
One micro coulomb is equal to
To store a large amount of charge at relatively low voltage, we use
If 1 joule of work is done against the electric field in bringing 1C positive charge from infinity to a point in the electric field then the potential at that point will be
If one negative particle is 1.6×10-19, then the charge of how many particles would be equal to 100µC?
In coulomb's law, the force of attraction or repulsion between two charges is
The ability of a capacitor to store charge is affected by
In the presence of a charged body, an insulated conductor develops a positive charge at one end and a negative charge at another end. This process is called
The study of charges at rest is called
By using electroscope, if the body is negatively charged then due to electrostatic induction, then on the disk there will be appear
The electron in a hydrogen atom experiences an electric field from the atom's nucleus in the order of
The lines of the electric field were introduced by
A charge in the electric field always
Due to electrostatic induction in aluminum rod due to charged plastic rod, the total charge on the aluminum rod is
A person standing inside "Faraday cage" is not affected by the electric field because
Unlike charges always
The electric field 30cm away from a light bulb is roughly
Like charges always
In the combination of capacitors in series, the right plate of one capacitor is connected to the next capacitor's
