Electricity- Charge, Current, Voltage , Emf : Class 10 Physics

Electricity:   electricity facts

Charge:

• The physical property which determine the deficit or excess of electrons in body is called charge.
• charge is an intrinsic  property of matter.
• Its SI unit is coulomb.
• It is scalar quantity.

Magnetism

Magnetic Effect Of Electric Current

• A current carrying conductor produces a magnetic field around it. In other words, electric current can produce magnetism. This Phenomenon is called 'magnetic effect of electric current.

ELECTROMAGNETIC INDUCTION

ELECTROMAGNETIC INDUCTION:  ELECTRICITY FROM MAGNETISM

• Magnets can produce emf  in wire  ( conductor ). The production of electrical energy from magnetism is called electromagnetic induction.

• The current produced in conductor due to magnetism is called induce current or induction current
