Description |
Italiano: Tipico strumento di misura elettrico di forma circolare, è montato su un supporto in legno per consentirne l'utilizzo in un laboratorio didattico. La struttura principale è sostanzialmente metallica ma lo strumento è caratterizzato da una finestrella in vetro, anch'essa di forma circolare, attraverso la quale è possibile effettuare la lettura della grandezza fisica misurata, in questo caso l'intensità di corrente elettrica. L'indice per la lettura scorre su una scala graduata, che ha la forma di un arco di circonferenza, permette ndo misure tra 0 e 2 Ampere Sulla base in legno che funge da supporto sono posizionati i due morsetti ai quali collegare gli estremi del circuito da misurare.
