DC VOLTAGE- or Direct current voltage
-
Is a Direct current Voltage which has
unidirectional flow of charge.
-
It is produced by batteries,
thermocouple, solar cells and in such generator.
-
It introduced by a power system that
has only one path of voltage and current.
-
It has single polarity, zero-frequency
and has constant voltage and current.
There are two types of DC voltage,
the dependent voltage and the independent voltage.
Independent
voltage is a circuit element that maintains a prescribe voltage across its
terminals regardless of current trough it.
That Dependent Voltage is said to be a source of voltage or
current at some part of the circuit that determines the voltage across its
terminals.
Voltage means Energy per Unit of
charge
Formula:
Voltage V= W / Q
W = stands for the energy that use in
unit of Joules
Q = stands for the unit of charger in
coulombs
Current is the charge flowing
in the circuit in the moment of time.
Current I= Q / t
I = stands for the current
Q = stands for the unit of
charger in coulombs
T= stands for the time that a charge
flow in seconds.
DC circuits – is a loop of circuits
that consist basically of different DC conducting wires. Flows with a DC charge
and DC voltage. Some of its composition are, Transistors, resistors,
capacitance inductors and Etc...
