A ground is simply a large object that serves as an almost innite source of electrons or sink for electrons. A negative charge is the result of acquisition of electrons. Charge does not flow easily through a super conductor. Induction is the transfer of charge by contact with an already charged object A material that behaves sometimes like a conductor and sometimes like an insulator is called a semiconductor. If a positively charged rod is brought near a neutral pith ball, the pith ball will move whom the rod. An electric charge has both direction and magnitude. insulators provide a good path to the electric current because they contain loosely bound [free to move] electrons in their atoms. Silver is a precious and costly metal, so it is not commonly used in the electric circuits. Good insulators provide very Mgh resistance to electric current so that it can't flow through it. The material that is a good conductor of electric current also conducts M easily. Conductors are the materials which resist or block the electric current from passing through them. A Wheatstone bridge circuit consists of four arms of which two arms consist of known resistances while the other two arms consist of an unknown resistance and a variable resistance. The force of magnetism is stronger when magnets are farther apart. Small magnets have weaker magnetic force compared to bigger magnets. The magnetic force of a bar magnet is strongest on its polia nd weaker on sides. Unmagnetized iron can be attracted to a permanent magnet. The pole of the magnet that orients northward is called the north pole Magnets can be magnetized by heating and/or dropping
