3. ELECTRIC
FIELD
An electric charge produces an
electric field, which is a region
of space around an electrically
charged particle or object in
which an electric charge would
feel force.

4. TABLE OF CONTENTS
Electric field is defined as
the electric force per unit
charge.
Explain The
Electric
Field.
Electric Field
Intensity.
A measure of the force
exerted by one charged
body on another.
Lines Of
Forces.
The imaginary line that
represents a field of force,
such as an electric or
magnetic field.
Properties Of
Lines
Of Forces.
Electric lines of force are
discontinuous curves.

6. ● ELECTRIC FIELD
The region around a charged particle
within which another charged particle will
experience an electrostatic repulsive or
attractive force is called the electric field.
Electric field is also called an electrostatic
field. The electrostatic force or electric
force is exerted by the static electric
charges I.e. electrons and protons.

7. ❖ TYPES OF ELECTRIC
FIELD
The electric fields are of four types:
● Uniform electric field
● Non-uniform electric field
● Static electric field
● Time varying electric field
● Uniform electric field

9. ❏ ELECTRIC FIELD
INTENSITY
Electric field strength can be mathematically defined as
force per unit charge
As we know that force is measured in Newton’s and charge is
measured in coulombs. Hence, electric field strength is measured
in Newtons per coulomb (N/C).

10. ❏Electric Field
Here, q0 is a “test charge” – it serves to allow the electric
force to be measured, but is not large enough to create a
significant force on any other charges.

11. ❏Electric Field
If we know the electric field, we
can calculate the force on any
charge:
The direction of the force depends on the
sign of the charge – in the direction of the
field for a positive charge, opposite to it for
a negative one.

13. We know that, when a unit
charge or point charge is placed
in the electric field of another
charged particle, it will
experience a force.
The direction of this force can
be represented by the imaginary
lines. These imaginary lines are
called electric lines of force.

15. PROPERTIES OF LINES OF FORCES:
1) The electric lines of force start from a positive
charge and end on a negative charge.
2) The electric lines of force always enter or leave
the charged surface normally.
3) Electric lines of force can never intersect each
other.
4) The electric lines of force cannot pass through
a conductor.
5) When two opposite charges are placed close to
each other, the electric lines of force present
between them will become shorter in length.
6) When two like charges are placed closer to
each other, the electric lines of force present
between them will become enlarged in length.
