3.4 How are circuits used in practical applications?

Practical ElectricityIMPORTANT! Technically electrons flow through circuits from the negative side of a battery to the positive side of a battery. HOWEVER, conventional current is assumed to flow from the positive end to the negative end. The discretion was caused during the discovery of electricity by Benjamin Franklin. By the time the mistake was discovered conventional current flow was well established, even though technically the flow is from negative to positive. Read more about this on allaboutcurrents.com.
