An electrical circuit (also known as an electrical network or electric circuit) is an interconnection of variousactive and passive componentsin a prescribed manner to form a closed path.Electric currentmust be able to flow from the source through some conductive medium and then back to the other ...
Electricity is used to power most everything people use today. Computers use electricity, light bulbs use electricity, and even some cars use electricity. Answer and Explanation:1 An electrical circuit is a path through which electricity flows. This path needs to make room for electricity to ente...
What is Ohms Law? Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and inversely related to the electrical resistance between the two points. This relation is shown in the fol...
You may have heard of WiMo, Brian's Windows Mobile®-based robot, an illustration of which is shown inFigure 1. WiMo has gained some notoriety for being a fully programmable robot that you don't need to be an Electrical Engineer to build. Brian, in classic Microsoft style, sees t...
In solid state electronic deviceand integrated circuitapplications,a semiconductor is required which must be crystalline and must contain a carefully controlled concentration(or volume density)of specific impurities. Semiconductor containing at least two specific impurities is needed for the following two fun...
