V dne\u0161nej dobe je v\u00e4\u010d\u0161ina zariaden\u00ed nap\u00e1jan\u00e1 na elektriku. Napr\u00edklad ako svetl\u00e1, dom\u00e1ce spotrebi\u010de, ale taktie\u017e aj zariadenia, ktor\u00e9 nemusia by\u0165 pripojen\u00e9 cez k\u00e1bel a dost\u00e1va\u0165 st\u00e1le striedav\u00e9 nap\u00e4tie. Elektrika m\u00e1 mnoho vyu\u017eitia a st\u00e1le sa prid\u00e1vaj\u00fa nov\u00e9 a nov\u00e9 vyn\u00e1lezy z v\u0161etk\u00fdch odvetv\u00ed do dne\u0161n\u00e9ho priemyslu a v\u00fdroby. Pr\u00fad je vlastne fyzik\u00e1lna veli\u010dina, ktor\u00e1 sa vyskytuje a vytv\u00e1ra v elektrike pri zapojen\u00ed elektrick\u00fdch spotrebi\u010dov. Ten sa vie vytvori\u0165 za pomoci elektrick\u00e9ho nap\u00e4tia, \u010do je v podstate rozdiel dvoch potenci\u00e1lov a to plus a m\u00ednus. Pri striedavom nap\u00e4t\u00ed sa vytv\u00e1ra takzvan\u00e1 s\u00ednusoida, \u010do je v podstate striedanie z\u00e1porn\u00e9ho a kladn\u00e9ho sign\u00e1lu. M\u00f4\u017ee tu by\u0165 taktie\u017e aj jednosmern\u00e9 nap\u00e1janie, ktor\u00e9 m\u00e1 ozna\u010denie DC, na druh\u00fa stranu tu je striedav\u00e9, ktor\u00e9 sa ozna\u010duje AC. Ka\u017ed\u00e9 zariadenie m\u00e1 taktie\u017e aj elektrick\u00fd v\u00fdkon a ten sa ud\u00e1va vo Wattoch pod\u013ea zn\u00e1meho vyn\u00e1lezcu Jamesa Watta. Ten vyna\u0161iel napr\u00edklad parn\u00fd stroj, \u010do sa stalo ve\u013ek\u00fdm vyu\u017eit\u00edm pre viacer\u00e9 odvetia vtedaj\u0161ej aj dne\u0161nej doby. A taktie\u017e nesmieme zabudn\u00fa\u0165 aj na fyzik\u00e1lnu veli\u010dinu, ktor\u00e1 je elektrick\u00fd odpor, ktor\u00e1 m\u00e1 taktie\u017e ve\u013ea spolo\u010dn\u00e9ho s zdrojmi elektrick\u00e9ho nap\u00e4tia. Ako u\u017e z n\u00e1zvu elektrick\u00fd odpor vypl\u00fdva tak odporuje vo\u010di nie\u010domu. Odpor vieme zisti\u0165 pomocou podielu nap\u00e4tia a pr\u00fadu.
