Electrons are distributed in orbital rings around the nucleus.
The distribution of electrons determines the atom’s electrical stability.
The electrons in the orbital ring farthest from the nucleus are especially important.

Information and Communication TechnologyHal.: 12 Electric Charge
ELECTRIC CHARGE
Most common applications of electricity require the charge of billions of electrons or protons.
1 coulomb (C) is equal to the quantity (Q) of 6.25 × 1018 electrons or protons.
The symbol for electric charge is Q or q, for quantity.

ELECTRIC CHARGE
Negative and Positive Polarities Charges of the same polarity tend to repel each other. Charges of opposite polarity tend to attract each
other. Electrons tend to move toward protons because
electrons have a much smaller mass than protons.

ELECTRIC CHARGE
An electric charge can have either negative or positive polarity. An object with more electrons than protons has a net negative charge (-Q) whereas an object with more protons than electrons has a net positive charge (+Q).
An object with an equal number of electrons and protons is considered electrically neutral (Q = 0C)

ELECTRIC CHARGE
Charge of an Electron The charge of a single electron, or Qe, is 0.16
× 10−18 C. It is expressed
• −Qe = 0.16 × 10−18 C
• (−Qe indicates the charge is negative.)
The charge of a single proton, QP, is also equal to 0.16 × 10−18 C .
However, its polarity is positive instead of negative.

Information and Communication TechnologyHal.: 17 The Volt Unit of Potential Difference
THE VOLT UNIT OF POTENTIAL DIFFERENCE
Potential refers to the possibility of doing work.
Any charge has the potential to do the work of moving another charge, either by attraction or repulsion.
Two unlike charges have a difference of potential.
Potential difference is often abbreviated PD. The volt is the unit of potential difference. Potential difference is also called voltage.

Information and Communication TechnologyHal.: 18 The Volt Unit of Potential Difference
THE VOLT UNIT OF POTENTIAL DIFFERENCE
The volt is a measure of the amount of work or energy needed to move an electric charge.
The metric unit of work or energy is the joule (J). One joule = 0.7376 ft·lbs.
The potential difference (or voltage) between two points equals 1 volt when 1 J of energy is expended in moving 1 C of charge between those two points.

ELECTRIC CURRENT
When the potential difference between two charges causes a third charge to move, the charge in motion is an electric current.
Current is a continuous flow of electric charges such as electrons.

Information and Communication TechnologyHal.: 21 Electric Current
ELECTRIC CURRENT
The amount of current is dependent on the amount of voltage applied.
The greater the amount of applied voltage, the greater the number of free electrons that can be made to move, producing more charge in motion, and therefore a larger value of current.
Current can be defined as the rate of flow of electric charge. The unit of measure for electric current is the ampere (A).
1 A = 6.25 × 1018 electrons (1C) flowing past a given point each second, or 1A= 1C/s.
The letter symbol for current is I or i, for intensity.

Information and Communication TechnologyHal.: 22 Resistance
RESISTANCE
Resistance is the opposition to the flow of current.
A component manufactured to have a specific value of resistance is called a resistor.
• Conductors, like copper or silver, have very low resistance.
• Insulators, like glass and rubber, have very high resistance.
The unit of resistance is the ohm (Ω). The symbol for resistance is R.

VARIABLE RESISTOR
Potentiometers Potentiometers are three-
terminal devices. The applied V is input to the
two end terminals of the potentiometer.
The variable V is output between the variable arm and an end terminal.

OHM’S LAW
The three forms of Ohm’s law can be used to define the practical units of current, voltage, and resistance:
• 1 ampere = 1 volt / 1 ohm• 1 volt = 1 ampere × 1 ohm • 1 ohm = 1 volt / 1 ampere

ELECTRIC POWER
The basic unit of power is the watt (W).• Multiple units of power are:
– Kilowatt (KW): 1000 Watts or 103 W
– Megawatt (MW): 1 Million Watts or 106 W
• Submultiple units of power are:– milliwatt (mW):
1-thousandth of a watt or 10-3 W– microwatt (μW):
1-millionth of a watt or 10-6 W

ELECTRIC POWER
Work and energy are basically the same, with identical units.
Power is different. It is the time rate of doing work.
• Power = work / time.• Work = power × time.

Practical Units of Power and Work: The rate at which work is done (power) equals
the product of voltage and current. This is derived as follows:
