2. Zaži karkiya. Yana da mafi sauki don sarrafa O-dimbin yawa Magnetic core (da haihuwa TV). Za mu iya amfani da wani, wanda giciye sashe ne karami fiye annabta daga dangantaka: P 1 = S * S / 1,44, inda P1 da S - gidan wuta ikon a watts da core giciye-sashe a cikin square cm. A lissafi ba a darajar S = 10,2 cm2.

3. A mataki na gaba shi ne mafi muhimmanci a cikin "yi" na gidan wuta - ne m da yawan jũya a kan 1B: N = 50 / S = 50 / 10.2 = 4.9 jũya / a.
