There
are three types of basic circuit components. They are
1.
Resistance
2.
Inductance
3.
Capacitance
Resistance:
It
is the property of a material to restrict the flow of electrons. It is denoted
by
R
and unit is Ohm (22). The symbol of resistance is shown in fig. 1.1.
Ohm:
It
is defined as the resistance offered by the material when a current of one
ampere flows between two terminals with one volt applied across the terminals.
According
to ohms law
The
power absorbed by the resistor is
P
= VI
P
= (IR)I
P
= 12 R
P = VI
Power
dw
= P dt
Integrate
on both the sides
Inductance:
Inductance
is a storage element which can store the energy in the form of electromagnetic
field. The symbol is shown in fig 1.2. It is denoted as L and unit is Henry
(H).
The
current voltage relation is
Integrating

The
power absorbed by the inductor is
The energy stored by the inductor is
Capacitance:
Capacitance
is a storage element which can store and deliver energy in the form of electric
field. It is denoted as C and unit is Farad (F). The symbol of capacitance is
shown in fig 1.3.
Current
through the capacitor is
Integrating
both the sides
The
power absorbed by the capacitor is
The
energy stored by the capacitor is
