Ag baint úsáide as peann tástálaí Voltais chun solas ciorcaid a thomhas, an mbeidh leictreachas ag an gciorcad? Cad is féidir dul mícheart?
What is "electricity"
First of all, we have to figure out what is "electricity". Under normal circumstances, what we call "electricity" means that a continuous and stable current can be generated in the circuit, and the current must be large enough - at least as large as Just to make the appliance work.
Chun na ceanglais seo a chomhlíonadh, ní mór na trí riachtanas seo a leanas a chomhlíonadh:
1. Ní mór go mbeadh voltas cobhsaí sa líne;
2. Ní féidir leis an luach voltais a bheith ró-íseal;
3. Caithfidh an líne a bheith ina lúb dúnta iomlán.
Mar sin, an féidir na trí thorthaí seo a thomhas le leictreascóp amháin? Is é an freagra ar bith!
