Electricity cannot always be generated where and when it is needed, so batteries are used in instances where direct current is needed and/or there is no access to a power outlet, or a cord becomes cumbersome. A battery is a device where chemical energy is converted
This course introduces the student to the purpose, function, and elements of the ubiquitous DC (direct current) power supply. Modern electronic devices generally require low-voltage DC sources to power their circuits. Some devices use battery or even...
Batteries are the backup power source for millions of consumer, business, medical, military, and industrial equipments worldwide. The critical applications such as computers, servers, instruments, telecommunications or life saving equipments require 100%...
A direct current generator, or DC generator, produces a voltage of constant polarity, which means the voltage and current do not change over time. DC generators are basically AC generators whose output voltage is switched the other way around at the proper moment,.
This course is intended to benefit engineers who design, use, inspect, or repair circuits that contain DC power sources and accompanying DC components. Application of DC circuits includes control, instrumentation, and motor excitation.
Whereas both AC and DC ci
Most students of electricity begin their study with what is known as direct current (DC). This is different than static electricity, which typically collects on the surface of a non-conductor such as a piece of plastic. It is also different than alternating current
Direct current or DC electricity is the continuous movement of electrons from an area of negative (-) charges to an area of positive (+) charges. A DC circuit is necessary to allow the current or stream of electrons to flow. Such a circuit consists of a source of..
