Voltage and Current Characteristics of Resistors
The resistor is an electrical device whose primary function is to introduce resistance to
the flow of electric current. The magnitude of opposition to the flow of current is called the
resistance of the resistor. A larger resistance value indicates a greater opposition to current
flow. The resistance is measured in ohms. An ohm is the resistance that arises when a current
of one ampere is passed through a resistor subjected to one volt across its terminals. The vari-
ous uses of resistors include setting biases in p-n junction, controlling gain, fixing time con-
stants, matching and loading circuits, voltage division, and heat generation.
The resistance of a resistor is directly proportional to the resistivity of the material and
the length of the resistor and inversely proportional to the cross-sectional area perpendicular
to the direction of current flow. Resistivity is an inherent property of materials. Good resistor
materials typically have resistivities between 2  10-6 and 200  10-6 ·cm.
The resistance can also be defined in terms of sheet resistivity. If the sheet resistivity is
used, a standard sheet thickness is assumed and factored into resistivity. Typically, resistors
are rectangular in shape; therefore the length l divided by the width w gives the number of
squares within the resistor. The number of squares
multiplied
by
the
resistivity
is
the
resistance.
The resistance of a resistor can be defined
in terms of the voltage drop across the resistor and
current through the resistor related by Ohm’s law.
Whenever current is passed through a resistor, a
voltage is dropped across the ends of the resistor.

i would like to tell you a horrible story. one night it seemed to me

that there was someone besides me in my room. i opened my eyes and saw a

woman's shade at the window . she was very tall, thin and she stretched out her

arms to me. i was scared and i screamed so loud as i could. i was sitting on

the bed and crying. suddenly my parents ran into my room. they were very

frightened. dad turned on the light, and i stopped screaming. it turned out

that in the afternoon, my mother brought a huge palm tree in a large pot from

the hall into my room and she put it behind the curtains. that night there was

full moon, and it seemed to me that it was a i have never been so bad as that

перевод

я хочу рассказать жуткую . однажды ночью мне

показалось что в моей комнате есть кто-то кроме меня. я открыл глаза и увидел у

окна тень. она была высокая, худая и протягивала ко мне руки. мне стало

страшно и я закричал так громко как только мог. я сидел на кровати и кричал.

вдруг в комнату вбежали мои родители. они были напуганы. папа включил

свет, и я перестал кричать. оказывается, днем мама принесла из зала в мою

комнату огромную пальму в большом горшке и поставила ее за штору. ночью была

полная луна и мне показалось, что это мне никогда не было так

страшно как в ту
