AC and DC in Physics - Essay Example

A rectify is a current-switching organization used in a circuit which comprises electronic elements that let electric current move in only one direction.

On the other hand, a DC (Direct Current) supply can be converted into an AC (Alternating Current) supply via using a motor-generator set or an inverter (Coles, 2012).

The ability for reverse movement of current in an AC (Alternating Current) circuit is because there is usually a rotating magnet along the wire.

Current flows in one direction in a DC (Direct Current) setup because there is a steady magnetism long the conducting wire.

In an AC (Alternating Current): Can transfer a large voltage volume. It is safe for the transference between big cities in different and far-off geographical locations.

In a DC (Direct Current): The voltage within a DC supply cannot travel a long distance simply because the circuit loses energy with an increase in coverage

In an AC (Alternating Current): The frequency usually ranges between 50Hz and 60Hz. This depends on the locality or country of operation.

In a DC (Direct Current): In this case, the frequency of DC (Direct Current) is zero

An instance source for AC (Alternating Current) includes an A.C Generator and mains (Brennan & Goldberg, 2012).

Electric transformers are mainly used to aid in either increasing or reducing the voltage throughput, a feature called stepping up or down of power.

It is advantageous since it allows the transmission of high electric voltage over a long distance at a low current capacity (El-Sharkawi, 2012).

Requires an increased level of insulation to ensure and safeguard the handlers. This increases the difficulty in safe handling which can cause a threat of electric shock to the handler. Heavy insulation proves to be an expensive material to implement (Grigsby, 2013).

Direct Current (DC) circuits frequently have diverse types of fixtures, switches, connectors, and sockets. It is applied mostly in this way since there is little voltage used (Herman & Loper, 2012).

AC is normally used to power cities and residential areas via the use of transformers which are usually located on streets on electrical poles. Consequently, the transformers also convert very high voltages into lower voltages which is suitable for use with home appliances, for example, refrigerators, TVs, and electric lamps (Keljik, 2013).
