Why is current measured by ammeter?

since theammeteris connected directly into the circuit, it must have a low resistance so that it does not reduce the flow of charge, which it is being used tomeasure current.

State and Explain Coulomb's Law in Electrostatic.

Why is the upper portion of a lightning rod always pointed?

Lightning rods are pointed so a charge will be concentrated at the end. If the rod had a round end the charges would spread equally around its surface. ... As long as the air is prevented from ionizing it won't conduct the lightning bolt.

What is meant by electric wind?

What is the name for wind electricity?

Wind energy (or wind power)describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.

Why repulsion is the sure test of electrification?

What is relation between Coulomb and Stat Coulomb?

Coulomb is the unit of electric charge which is defined as the amount of electric charge that passes through a surface at the rate of one ampere per second. The coulomb is abbreviated as "C".

The statcoulomb (abbreviated as "statC") is a unit of electric charge that is equal to the amount of charge in 1 statcoulomb of charge. One statcoulomb is defined as the charge that is transported in one second by a current of one statampere. The statcoulomb is a unit that is used in the CGS system of...

What do you mean by quantization of charge? Explain.

We often experience the sparks during winter nights when removing our clothes from our bodies. Why?

How can a pith ball be electrified with a positive or negative charge?

Can a charged body attract an uncharged body? Explain.

Why is it dangerous to sit under a tree when it is lightening?

A charge q is divided into two small conducting spheres. Calculate the value of charges on the spheres so that when they are placed at certain distance apart, the repulsive force between them is ma...
