• Class 10 Science Electricity  In this article,
  we will discuss an important topic from Class 10
  Science Electricity notes.
• Now, the first question arises in the mind of
  the 10 Class Science student, can we live without
  electricity? The answer is No.
• What is Electricity?
• Electricity is an important source of energy in
  the modern times. It is used in our homes for
  lighting, operating fans, trains, etc. The
  ability to attract anything is called electric
  charges.
• Electric charges
• It has been scientifically proven that the
  electric charges are of two types- positive
  charges and negative charges. The charge acquired
  by a glass rod is called positive charge and the
  charge acquired by an Ebonite rod is called
  negative charge.
• Lets discuss the property for electric charges
  are
• Opposite charges attract each other.
• Similar charges repel each other.

• The SI unit of electric charge is Coulomb which
  is denoted by the letter C. All the matter around
  positively charged particles called protons and
  negatively charged particles called electrons.
• A proton possesses a positive charge of 1.6 X
  Whereas electron possesses a negative charge 1.6
  X .
• Conductors and Insulators
• A conductor is a substance through which
  electricity can flow. Eg- Silver, copper,
  aluminum, etc.
• Insulators are the substances through which
  electricity cannot flow are called insulators.
  Eg- Glass,Ebonite, rubber, etc.
• Moving forward, now understand how the conductors
  work?
• All the conductors have some electrons which are
  loosely held by the nuclei of their atoms. These
  electrons are called Free electrons and can
  move from one atom to another atom throughout the
  conductor. The presence of free electrons in a
  substance makes it a conductor.
• Electricity can be divided into two parts-
• Static electricity-In this electrifying, the
  electric charges remain at rest as they do not
  move.
• Current electricity-In this electrifying, the
  electric charges are in The electricity we use it
  in our homes is called current electricity.

•   Electric Potential
• Work done in moving a unit positive charge from
  infinity to a point is called the electric
  potential at that point in an electric field.
• The potential is denoted by the symbol V and
  its unit is volt.
• Potential Difference
• The amount of work done in moving a unit charge
  from one point to the other point is defined as
  the potential difference between two points.
• Potential difference work done/quantity of
  charged moved.
• The SI unit of potential difference is volt and
  which is denoted by the letter V.
• The potential difference between two points is
  said to be 1 volt if 1 joule of work is done in
  moving 1 coulomb of electric charge from one
  point to the other.
• 1 volt1joule/1coulomb

• The potential difference is measured by means of
  an instrument called aVoltmeter. A voltmeter has
  a high resistance so that it takes a negligible
  current from the circuit. Voltage is the other
  name for potential difference.
