This necessitated people to work hard to pursue higher education which was perceived to be a direct ticket towards its accomplishment. However, this dream was threatened after the ...

Electricity can flow in two different ways; either in direct current (DC) or in alternating current (AC). Electricity is a moving electron through or along a conductor, for instance a wire, which have been connected for energy (Daly, Peckham & AudioGO, 2013). Therefore, the variation between DC and AC is the direction of electron flow. In direct current, the electrons flow in one direction (forward). In alternating current, electrons keep changing directions, sometimes forward and at times backwards (Daly, 2013).

Origins of DC and AC Current

A magnetic field next to a wire can make electrons flow along the wire in one direction, because electrons become repelled from the negative ...

A fire alarm system detects the presence of fire by monitoring the changes associated with combustion. The early response towards a fire attack yields positive results. The fire alarm systems protect loss of lives and property by alerting responsible people to stop the fire. From recorded history, people knew this and there existed ways to alert people to respond to a fire in a place. They used hand bell-ringers, factory steam whistles and church bells to get the attention of the fire brigade. Unfortunately, this equipment did not give much detail and they often directed the fire department to the wrong direction.
