LIGHTENING

ELECTRIC FIELD

Q1

:

What causes li
ke charges to repel and
unlike
charges to attract?

:

This is bec
ause a charged object exerts
an
e
lectrostatic force (that is
attractive

force or
repulsive force) on
nearby objects.

ELECTRIC FIELD LINES

The direction of electrostatic forces
experienced by two opposite charges
(electrodes) in electric field.

Electric field lines are directed from
positive charge (electrode) to
negative charge (electrode)
.

This figures show the direction of
the

electrostatic forces…..

APPENDIX

1

The closer the electric fields lines, the
stronger electrostatic forces.

The electric field lines neither branch
off nor intersect one another.

Effect of Electric Field Acting On A

Charged Body

Van de Graaff

Electric field is formed by using a
Van de Graaff generator.

Charges are transmitted to body when
person touch the generator.

Human body form
s an electric field
around it.

The hairs stand on the ends because
they carry like charges and repel each
other.

CHARGE FLOW

Negative electric charges which are carried
by

electrons are “pushed” from the
negative terminal (
-
) of the cell.

These electrons go through the circuit
and back to the positive terminal (+) of
the cell.

This flow of electric charges forms an
electric current
.

ELECTRIC CURRENT

Is defined as the rate of charge flow,
that is

Where Q is the quantity of charge
flow and t is the time taken

The unit of
electric current is ampere
(A)

The unit of the quantity of charge
flow is coulomb (C).

Hence, 1A = 1Cs¯¹

TYPE OF AMMETERS

Electric current is measured by using an
ammeter, a milliammeter or a microammeter
