ATOM

An atom is a fundamental unit of matter

made up of :

protons (with a positive charge)

neutrons (neutral – no charge)

electrons (with a negative charge)

CHARGE Charge is a intrinsic property of sub-atomic

particle

CURRENTFLOW OF CHARGES IS CALLED CURRENT(I)

CHARGE,TIME AND CURRENTRELATION:

t

QI

AMPHERE

If one columbs charge passes in one

second then one ampere current is

said to be produce

ELECTRIC COMPONENTS AND SYMBOLS

ELECTRIC CIRCUIT

THERE ARE 2TYPES OF CIRCUITS THEY ARE

1)OPEN CIRCUIT

2)CLOSED CIRCUIT

CLOSED CIRCUIT

a. Has Multiple paths

b. A break in one

load & the other loads

stay on

c. Voltage is the same

in each load,but

current and resistance

may be different

Parallel circuit

a. Has only One path

b. voltage is different in circuit

c. Current is the same throughout the

circuit

Series circuit

CONDUCTORS,INSULATORS AND SEMICONDUCTOR

Semi conductor

conductors insulators

RESISTANCE

OPPOSITION CREATED TO THE FLOW OF CHARGES BY CONDUCTOR

OHMS LAW

It states that a constant temperature current is directly

proportional to voltage

George Simon Ohm was the man who invented ohm's law

in 1826. He was a physicist and a mathematician. He was

also a high school teacher where he started the research

with the electrochemical cell. He studied in Friedrich-Alexander-University.

SOLUTION AND THEIR TYPES

HOMOGENOUS

SOLUTION

HETROGENOUS

SOLUTION

ACQUEOUS SOLUTION

ELECTROLYTE NON-ELECTROLYE AND ELECTROLYSIS

ELECTROLYTE CONDUCTES ELECTRICITY

NON-ELECTROLYTE DO NOT CODUCTS THE

ELECTRICITY

ELECTROLYTE AND NON-ELECTROLYTE

ELECTROLYTE NON-ELECTROLYE AND

ELECTROLYSIS

ELECTORLYSIS

ELECTRODES,IONS AND THEIR TYPES

THERE ARE TWO TYPES OF ELECTODES THEY ARE:

1.ANODE(POSITIVE ELECTRODE)

2.CATHODE(NEGETIVE ELECTRODE)

ELECTRODES

IONS

THERE ARE TWO TYPES OF IONS THE ARE:

1.ANION(NEGATIVE ION)

2.CATION(POSITIVE ION)IONISATION

K CL+ _

MAGNETIC FIELD

A magnetic field is the region around a

magnet in which magnetic force is

detected

LED

THESE ARE USED FOR DETECTNG WEAK CURRET

ELECTROPLATING
