What makes charge flow in a circuit?
When one end of a wire (for example) is made negative and the other end positive, electrons in the wire have a force placed on them. They are repelled by the negative end and attracted to the positive end, so they move in the wire, carrying electrical charge. This flow of charge is described as electric current.
What are charges in a circuit?
Electrons are negatively charged particles and they transfer energy through wires as electricity. Charge is a property of a body which experiences a force in an electric field.
What is the source of charge?
Source charge-The charge which produce electric field and It is a large charge through which electric fields flow.It may be a point charges,or a continuous distribution of charges. Here the range of any source charge around space Is infinity,that is Electric field extends till infinity.
Where does electric current come from?
Most of the electricity that we use comes in the form of alternating current (AC) from the electric power grid. Alternating current is produced by electric generators that operate on Faraday’s Law of Induction, by which a changing magnetic field can induce an electric current in a conductor.
Who discovered the charge?
Positive and negative values of charge were originally assigned by the American statesman and inventor Benjamin Franklin, who started studying electricity in 1742. Until then, most people thought that electrical effects were the result of mixing of two different electrical fluids, one positive and one negative.
How the current is produced?
Electric current can be generated by moving a metal wire through a magnetic field. It is also different than static electricity, which is the accumulation of charges on a surface. Electric generators rotate a coil of wires through a magnetic field.
How is the current made?
When a voltage is applied to a conductor or semiconductor, electric current starts flowing. In conductors, positively charged protons are held in a fixed position and the negatively charged electrons move from one place to another place by carrying the charge. Thus, electrons conduct electric current in conductors.
